cmd(command) write on 4-wire spi-bus sck<=4mhz status read on 4- wire spi-bus sck<=4mhz 6.4 interrupt there are 2 kinds of interrupt events for lcm,each maps to the corresponding status bits in reg[f1h]: touch event occurs.bit 2 of reg[f1h] is set to 1. the font access is completed.bit 0 of reg[f1h] is set to 1. all of the above interrupts function can be enable/disable by setting intc1( reg[f0h]),in addition,if the system of customer can not provide the hardware interrupt,the lcm also supports a software polling method;mcu can detect the http://www..net/ datasheet pdf - http://www..net/
interrupt status through the related status flag.when hardware interrupts of lcm are active,the related interrupt masks must be disable first.there is an example for describing the interrupt procedure of touch panel as below lcm sends an interrupt signal to mcu. when mcu receives interrupt signal,the program counter(pc) will jump to isr start address. in the mean time,the corresponding interrupt status flag of lcm will be set to 1(reg[f1h]).for example,when touch event generates an interrupt,the touch panel interrupt status bit will be set to 1. after the isr completes,the status flag should be cleared ,i.e.,write 1 to the corresponding bit of status register. by software interrupt,user can read intc2 register for detecting interrupt event without any external device.besides,interrupt mask function is only applied to hardware interrupt,not to intc2 status flag.it should be noted that,intc2 status flag must be cleared manually at the tail of isr,i.e.,writing the bit2 of register intc2(reg[f1h])with 1,because the intc2 status flag will not be cleared automatically. 6.5 data format the lcm supports the 16-bit color depth tft-lcd panle,.i.e 65k colors tft lcd panel. color illustrations fo r 8-bit data bus mcu http://www..net/ datasheet pdf - http://www..net/
