(7) A/D port configuration register (ADPC)
This register switches the P20/ANI0 to P27/ANI7, and P150/ANI8 to P156/ANI14 pins to digital I/O of port or analog
input of A/D converter.
The ADPC register can be set by an 8-bit memory manipulation instruction.
Reset signal generation sets this register to 00H.

Cautions 1. Set the channel used for A/D conversion to the input mode by using port mode registers 2, 15
(PM2, PM15).
2. Do not set the pin set by the ADPC register as digital I/O by the analog input channel
specification register (ADS).
