(3) 10-bit A/D conversion result register (ADCR)
308
Symbol
ADCR
Caution 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 FFF1FH and the lower 2 bits are stored in the higher 2 bits of FFF1EH.
ADCR can be read by a 16-bit memory manipulation instruction.
Reset signal generation clears this register to 0000H.
Address: FFF1FH, FFF1EH
register (ADS), and A/D port configuration register (ADPC), the contents of ADCR 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.
