(4) 8-bit A/D conversion result register (ADCRH)
Caution When writing to the A/D converter mode register (ADM), analog input channel specification
This register is an 8-bit register that stores the A/D conversion result. The higher 8 bits of 10-bit resolution are
stored.
ADCRH can be read by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
register (ADS), and A/D port configuration register (ADPC), the contents of ADCRH may become
undefined. Read the conversion result following conversion completion before writing to ADM,
ADS, and ADPC. Using timing other than the above may cause an incorrect conversion result to
be read.
