HT13R90
Functional Description
Power On & Reset The HT13R90 has four different operating states, namely the POR state, the standby state, the running state and the wait state. The wait state can only be entered when the Operating Mode bits, known as OMOD, have a value of either 01 or 10. The POR state is the Power on state, during which the device internal clock will be used to load the configuration options. When the device is in the POR state, the output pins, LED0, LED1 and LED2, will remain in a tri-state condition. After the POR state has completed, if the RESET pin remains low, the device will then enter the standby state. In this state, the output pins will remain in an inactive state according to the configuration option settings.The
P O R S ta te ( L o a d O p tio n )
accompanying timing diagram gives more details. For the general case, the oscillator will cease running to reduce power, however the configuration options can also be set to keep the oscillator running in the standby mode in order to reduce the oscillator startup time. In modes 01 and 10, after the counting ends, the device will enter the wait state, which is different from what will happen if the RESET line goes low. The wait state encompasses the same behavior as the standby state. When the RESET line returns high, the device will enter the running state. At the beginning of this state, the configuration options will be loaded, which will initiate a reset, switch to the defined oscillator and start running.

Operating Modes The HT13R90 has 3 operating modes. MODE 0 is the continuous mode, MODE 1 is the single period mode and MODE 2 is the single pulse mode. The required mode is selected via the OMOD bits in the configuration options.

LED Waveform for Each Active State Note: To ensure the carrier pulse is visible at the onset of every pulse on the LED1 and LED2 pins, the carrier frequency, which is selected by the LxCARR configuration option bits, should be set to a higher value than the TMR0 prescaler frequency, which is selected by the PCR0M configuration option bits.To ensure that the LED1 and LED2 output pulses are visible at the onset of every active state, the output pulse frequency, which is selected by the LxFREQ configuration option bits should be higher than the TMR1 prescaler frequency, which is selected by the PCR1M configuration option bits

* Mode 0 - OMOD option bits set to 00
At power on, after the power on procedure has completed, the device will keep running continuously as long as the RESET line remains at a high level. If the RESET line should go low, the oscillator will stop and the LED0 pad will change to an inactive state. The device will then enter the standby state. Any time the RESET line goes low, the device will enter the standby state until the RESET line again goes high.
This mode is usually used for periodic turn on and turn off time setting applications. The LED0 pad output signal timing and state machine is shown below. Output Timing Diagram for OMOD = 0,0

At power on, after the power on procedure has completed, the device will start running. When the device is running, if the RESET line should go low, the device will enter the standby state until the RESET line returns to a high level. When the RESET line returns to a high level, the device will reload the configuration options and restart counting. If the RESET line does not change before the count has finished, it will automatically enter the standby state. When in the standby state, if the RESET line experiences a low to high edge, then the counting will restart. This mode can be used in practical applications to set a certain turn-on and turn-off time. The LED0 pad output signal timing and state machine is shown below. Output Timing Diagram for OMOD = 0,1

LED2 Complementary Function The LED2 output condition can be the same as the LED1 output, but can also be setup to be the complement of the LED1 output. There is a configuration option named L2CMP related to this setting. If L2CMP is set to zero, the LED2 output will be the same as the LED1 output. By utilising the other options which have either an L2 or L1 header, both LED2 and LED1 can be individually controlled. If L2CMP is set to one, the LED2 output will be the complement of the LED1 output. In this situation, only L2ACT and L2OUT will have an effect on the LED2 output. All other options with an L2 header will be ignored. In the complement situation, when the LED2 output is in its active state, then it will output the complementary waveform. If LED2 is in its inactive state, then it will keep its inactive state depending upon the L2ACT setting and the condition of the LED1 waveform. LED2 Complementary Timing Diagram for OMOD = 0,0

Oscillator Configuration There are 2 oscillator circuits within the device.
OSC1 OSC1
OSC2 C r y s ta l O s c illa to r RC
OSC2 O s c illa to r
If the Crystal oscillator is selected, a crystal connected between OSC1 and OSC2 is needed to provide the feedback and phase shift required for the oscillator. No other external components are required. Instead of a crystal, a resonator can also be connected between OSC1 and OSC2 to obtain the desired frequency reference, but two external capacitors between OSC1, OSC2 and ground are required. Note: The 32768Hz Oscillator has a quick start up design. This quick start function should automatically turn off after the clock has stabilised to reduce power consumption. The IRC circuit will provide the clock during the power-on option-loading stage. This is necessary as the choice of crystal or IRC is determined by the oscillator configuration option in the OTP memory. The IRC oscillator contains an adjustment configuration option, to enable the IRC frequency to be adjusted during device programming. This option has a total of 7 bits (128 sections).
Both circuits are designed for system clocks, namely the Internal RC oscillator (IRC) and the external Crystal oscillator (ECRY), the choice of which is determined by a configuration option. When in the standby state, the system oscillator stops running and all external signals are ignored to reduce power. The Internal RC oscillator provides the most cost effective method of clock implementation, however, when compared with the crystal oscillator, the frequency of oscillation may vary with VDD, temperature and process variations. It is therefore not suitable for timing sensitive operations where an accurate oscillator frequency is desired.
Configuration Options The following table shows the full range of Timer configuration options. All of the options must be defined to ensure proper system functioning.
