... Programmer can define which signal pattern is "0", and which signal is "1" For example, using Timer_interrupt to enable/disable PE2 function, and programmers can produce the signal pattern which means "0" or "1" The same way, receive side can decode the signal by encode information. 23/34 ST2608B ...

... It's RC osc signal. <IrDA mode application note> Since IrDA has strictly protocol when transmit/receive data. We suggest programmers use X’tal to be system clock instead of RC-OSC if IrDA signals are needed. Programmer can use ceramic-OSC to gain some profit since it’ s cheaper than X’ tal. 28/34 ST2608B ...

... For example: If baud rate = 9600bps and OSC is in the rage of 3.72~4.28MHz, programmer should set BRS=61, BDIV=13 to get the best output baud rate which has error of 0.1%.So the real output baud rate will be in the range of [9600x0.999:9600x1.001]. 29/34 ST2608B ...

... Vlcd voltage level : Higher Vlcd pays higher current. (4) Using EPROM will cost more current than no use. (5) Input without any connection will randomly cost power (6) WAIT mode with considerable program can save lots of power (7) Larger panel will pay more current. (8) Un-ideal hardware connection will cause unknown current waste. 30/34 ST2608B ...
