EM78P350N
8-Bit Microprocessor with OTP ROM
Bit 6 ~ Bit 5 (CKR1 ~ CKR0):The prescaler oscillator clock rate of ADC
00 = 1:16 (default value)
01 = 1: 4
10 = 1: 64
11 = 1: WDT ring oscillator frequency

Bit 4 (ADRUN): ADC starts to run
0 = reset on completion of the conversion. This bit
cannot be reset though software.
1 = an AD conversion is started. This bit can be set by
software.
Bit 3 (ADPD): ADC Power-down mode.
0 = switch off the resistor reference to save power even
while the CPU is operating.
1 = ADC is operating
Bit 2 ~ Bit 0 (ADIS2 ~ ADIS0): Analog Input Select.
000 = AN0/P60
001 = AN1/P61
010 = AN2/P62
011 = AN3/P63
100 = AN4/P64
101 = AN5/P65
110 = AN6/P66
111 = AN7/P67
These bits can only be changed when the ADIF bit and the ADRUN bit
are both low.
