8-bit Micro-controller

RA page2 bit4(PLUS) determine RAM address auto increase or not (only for multiplier’s addressing).

RA page2 bit7 is undefined.

“VERSEL” = 1: R8 page1 is undefined.

RA page2 bit4(PLUS) determine RAM address auto increase or not (for data RAM and multiplier’s

addressing).

RA page2 bit7(INS) determine .

RB page2 defined to multiplier’s Y data, Y address or data RAM address buffer.

7. The carry bit’s initial value is un-know, please define the initial value before execute first ADD or SUB instruction that

include carry bit.(VERSEL =1 and INS = 1)

8. In EM78569’s developing tool, “VERSEL” and “PHO” are at RD page2 bit6 and bit5, but in mask chip, these two bits

will mapping to code option. Please set these two bits to fixed value at initial and do not change these two bit

among your program.

9. While switching main clock (regardless of high freq to low freq or on the other hand), adding 6 instructions delay (NOP)

is required.

10. Please do not switch MCU operation mode from normal mode to sleep mode directly. Before into sleep mode, please

switch MCU to green mode.

11. Offset voltage will effect ADC’s result, please refer to figure 20 to detail.
