13.4.7
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.
