13.4.3 Single-Cycle Scan Mode
489
Deleted
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_1. 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_1, 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.
13.4.7 2-Channel Scanning
493
Added
In 2-channel scan mode, since the four channels of
analog input are divided into groups 0 and 1, triggers for
activation of groups 0 and 1 are independently
specifiable. Conversion end interrupts in 2-channel
scan mode can be generated either on completion of
group 0 or group 1 or on completion of group 0 and
group 1. If conversion is to be started by triggers, the
different sources for groups 0 and 1 are specified in
ADTSR. A request for conversion by group 1 generated
during conversion by group 0 is ignored. Figure 13.4
shows an example of operation when TRG4AN of the
MTU2 has been specified as the A/D conversion start
request by group 0 and TRG4BN of the MTU2 has been
specified as the A/D conversion start request by group
1.
