In 2-channel scan mode, since the channels are divided into
group 0 and group 1, even though group 0 is operating in
single-cycle scan mode, the contents of the A/D data registers
for group 1 are retained. Similarly, even though group 1 is
operating in single-cycle scan mode, the contents of the A/D
data registers for group 0 are retained. Note that a group 1
conversion request issued during group 0 A/D conversion is
ignored. Specify different trigger sources for the group 0 and
group 1 conversion requests so that a group 0 conversion
request is not generated simultaneously with a group 1
conversion request.
In 2-channel scan mode, when A/D conversion is to be started
by software, selection of group 0 or group 1 is determined by
the CH2 to CH0 bits in ADCSR_0 to ADCSR_2. When A/D
conversion is to be started by triggering, regardless of the
setting of the CH2 to CH0 bits in ADCSR_0 to ADCSR_2, A/D
conversion for group 0 is started by the trigger source set by
the TRG0S3 to TRG0S0 and TRG1S3 to TRG1S0 bits in
ADTSR, and A/D conversion for group 1 is started by the
trigger source set by the TRG01S3 to TRG01S0 and TRG11S3
to TRG11S0 bits in ADTSR.
