(5) A/D port configuration register (ADPC)
294
This register switches the P80/ANI0 to P87/ANI7, P90/ANI8 to P93/ANI11 pins to analog input of A/D converter or
digital I/O of port.
ADPC can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Cautions 1. Set the channel to be used for A/D conversion in the input mode by using port mode
