•
A/D Interrupt Enable
The A/D conversion end interrupt (ADI) request is
enabled when 1 is set
When changing the operating mode, first clear the
ADST bit in the A/D control registers (ADCR) to 0.
Reserved
This bit is always read as 0. The write value should
always be 0.
A/D Operating Mode Select
Selects the A/D conversion mode.
0: Single mode
1: Scan mode
When changing the operating mode, first clear the
ADST bit in the A/D control registers (ADCR) to 0.
Reserved
This bit is always read as 1. The write value should
always be 1.
Reserved
This bit is always read as 0. The write value should
always be 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
When the DMAC or the DTC is activated by an
ADI interrupt and data is read from ADDR while
the DTMR bit in the DTC is cleared to 0
