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 when the P20/ANI0/TI000/TOH1, P21/ANI1/TI010/TO00/INTP0, P22/ANI2, and P23/ANI3 pins
for analog input, set PM20 to PM23 and PMC20 to PMC23 to 1. At this time, the output latches of P20 to P23
may be 0 or 1.
PM2 and PMC2 are set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets PM2 to 00H and clears PMC2 to FFH.
Caution If PMC20 to PMC23 are set to 1, the P20/ANI0/TI000/TOH1, P21/ANI1/TIO10/TO00/INTP0,

P22/ANI2, and P23/ANI3 pins cannot be used for any purpose other than the A/D converter
function.
Be sure to set 0 to the Pull-up resistor option register of the pin set in A/D converter mode.
