This register is an 8-bit register that stores the A/D conversion result. It stores the higher 8 bits of a 10-bit
resolution result.
ADCRH can be read by an 8-bit memory manipulation instruction.
Reset signal generation makes ADCRH undefined.
When using the P20/ANI0 to P23/ANI3 pins for analog input, set PMC20 to PMC23 and PM20 to PM23 to 1. At
this time, the output latches of P20 to P23 may be 0 or 1.
PMC2 and PM2 are set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears PMC2 to 00H and sets PM2 to FFH.
Caution When PMC20 to PMC23 are set to 1, the P20/ANI0 to P23/ANI3 pins cannot be used as port
