(5) A/D port configuration register (ADPC)
Cautions 1. Set a channel to be used for A/D conversion in the input mode by using port mode register 2
This register switches the ANI0/P20 to ANI7/P27 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.
Address: FF2FH
Symbol
ADPC
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
details, see CHAPTER 35 CAUTIONS FOR WAIT.
