(7) Port mode registers 1, 2 (PM1, PM2)
Cautions 1. Set the pin set to analog input to the input mode by using port mode register 1 (PM1).
When using the ANI8/AMP1-/P10 to ANI10/AMP1+/P12 and ANI0/AMP0-/P20 to ANI7/P27 pins for analog input
port, set PM10 to PM12 and PM20 to PM27 to 1. The output latches of P10 to P12 and P20 to P27 at this time
may be 0 or 1.
If PM10 to PM12 and PM20 to PM27 are set to 0, they cannot be used as analog input port pins.
PM1 and PM2 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to FFH.
Remark A/D converter analog input pins differ depending on products.
