ADCR
Cautions 1. When writing to the A/D converter mode register (ADM), analog input channel specification
This register is a 16-bit register that stores the A/D conversion result. The lower 6 bits are fixed to 0. Each time
A/D conversion ends, the conversion result is loaded from the successive approximation register. The higher 8
bits of the conversion result are stored in FF09H and the lower 2 bits are stored in the higher 2 bits of FF08H.
ADCR can be read by a 16-bit memory manipulation instruction.
Reset signal generation clears this register to 0000H.

writing to ADM, ADS, and ADPC. Using timing other than the above may cause an incorrect
conversion result to be read.
CPU is operating on the subsystem clock and the peripheral hardware clock is stopped. For
