A/D Interrupt Enable
The A/D conversion end interrupt (ADI) request is
enabled when this bit is set to 1.
When changing the operating mode, first clear the
ADST bit in the A/D control registers (ADCRs) to 0.
A/D Mode 1 and 0
Select the A/D conversion mode.
00: Single mode
01: 4-channel scan mode
10: 8-channel scan mode
11: Setting prohibited
When changing the operating mode, first clear the
ADST bit in the A/D control registers (ADCRs) to 0.
For A/D2, the ADM1 bit must be cleared to 0.
Reserved
This bit is always read as 1. The write value should
always be 1.
Channel Select 2 to 0
Select analog input channels. See table 11.2.
When changing the operating mode, first clear the
ADST bit in the A/D control registers (ADCRs) to 0.
When A/D conversion ends in single mode
When A/D conversion ends on all specified
channels in scan mode
When 0 is written after reading ADF = 1
