(4) Analog input channel specification register (ADS)
(5) A/D port configuration register 0 (ADPC0)
Cautions 1. Be sure to clear bits 3 to 7 to “0”.
This register specifies the input channel of the analog voltage to be A/D converted.
ADS can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
This register switches the ANI0/P20 to ANI5/P25 pins to analog input (analog input of 16-bit
converter or analog input of 10-bit successive approximation type A/D converter) or digital I/O of port.
ADPC0 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 08H.
CHAPTER 12 10-BIT SUCCESSIVE APPROXIMATION TYPE A/D CONVERTER ( PD78F041x only)
2. Set a channel to be used for A/D conversion in the input mode by using port mode register 2
3. Do not set a pin to be used as a digital I/O pin with ADPC with ADS.
4. If data is written to ADS, a wait cycle is generated. Do not write data to ADS when the CPU is
(PM2).
operating on the subsystem clock and the peripheral hardware clock is stopped. For details,
see CHAPTER 29 CAUTIONS FOR WAIT.
