Note: a. File format must be binary and the extension should be ".BIN" . b. File should be wrapped in ZIP format for transferring or e-mailing. c. Only single file is allowed. d. File length equals to 131072 (128x1024) bytes. e. Functions should be checked on the emulation board or by real chip. f. Electric characteristics of the emulation board are not identical with those of the real chip.

DATE: CHECK NOTE
Check the desired frequency matched the VDD Check and use the updated version of data sheet After power on, enter wait-1 mode for 1.5 second before normal operation Initialize user RAM and every related control register Confirm contrast level, duty, frame rate, alternating rate and the display quality of LCD Before entering power down mode, turn off unused peripheral such as LCD controller, and LVD Confirm I/O direction, default state, and function enable bits. Enable pull-up for unused input pins Read from an input port after the signals are stable. Ex. when doing key scan, delay 12 us from a new scan value then read the return lines. If an input connects to VDD or GND directly, make sure to remove any DC current from internal pull-up/down resistor after the status is being read.
Do not use " read-modify-write" instructions, e.g. ROR and SMB0, to the registers

11 Disable unused functions and reserve "RTI" instruction for unused interrupt vectors 12 Check stack memory limited within 256 bytes. 13
Always disable interrupt function (by an ` SEI' instruction) when modifying the IENAL, IENAH, IREQL and IREQH registers.
14
Use a ST2203U real chip, together with the emulation mode, to development the whole system. Test and verify every condition
15 File length of released binary file must equals to 131072 (128x1024) bytes
