(4) A/D port configuration register (ADPC)
134
Cautions 1. Set the channel used for A/D conversion to the input mode by using port mode register 2
This register switches the P20/ANI0 to P27/ANI7 pins to digital I/O of port or analog input of A/D converter.
ADPC can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to 00H.

2. If data is written to ADPC, a wait cycle is generated. Do not write data to ADPC when the CPU
(PM2).
is operating on the subsystem clock and the peripheral hardware clock is stopped. For
