Section 17 A/D Converter (ADC)
17.3.5 A/D Data Registers 0 to 7 (ADDR0 to ADDR7)
ADDRs are 16-bit read-only registers. The conversion result for each analog input channel is
stored in ADDR with the corresponding number. (See table 17.4.)
The converted 12-bit data is stored in bits 11 to 0.
The initial value of ADDR is H'0000.
After ADDR is read, ADDR can be automatically cleared to H'0000 by setting the ACE bit in
ADCR to 1.
