Application Note
1. 2.0V reference voltage will power down when both RD PAGE2 bit7(DAREF) and RA PAGE2 bit7(CMPEN) are clear
to 0.
2. For targeting interrupt and program run to address 0x0008, ACC, R3(STATUS), R5(Program page) and R4(6,7) will
be automatically saved and R3(6,7) R register page will set to PAGE0, and reload after the instruction “RETI”.
3. Before using Key tone function, please set Port 76 as output type.
4. In EM78R813, pin EGIN1 and EGIN2 are shared with pin TIP and RIN, but they are independent in EM78P813 and
EM78813.
5. In EM78R813, user can turn on one of FSK, DTMF and CW power at the same time. In OTP and mask version, user
can turn on both CID(one of FSK and DRMF) or CW power at the same time, but FSK and DTMF power can not turn
on simultaneously.
6. Please do not switch MCU operation mode from normal mode to sleep mode directly. Before into sleep mode, please
switch MCU to green mode.
7.For accessing data ROM,EM78P813 (OTP) can work at 10.74MHz, but please note that ROM type EM78813 only can
work at 5.37MHz
8. While switching main clock (regardless of high freq to low freq or on the other hand), adding 6 instructions delay (NOP)
is required.
