Description
A/D Trigger 0 Select 3 to 0
Select an external trigger or MTU2 trigger to start A/D
conversion for group 0 when A/D module 0 is in single
mode, 4-channel scan mode, or 2-channel scan mode.
0000: External trigger pin (ADTRG) input
0001: TRGA input capture/compare match for each
0010: MTU2 channel 0 compare match (TRG0N)
0011: MTU2 A/D conversion start request delaying
0100: MTU2 A/D conversion start request delaying
0101: Setting prohibited
0110: Setting prohibited
0111: Setting prohibited
1xxx: Setting prohibited
When switching the selector, first clear the ADST bit in
the A/D control register (ADCR) to 0.
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.
MTU2 channel or TCNT_4 underflow (trough) in
complementary PWM mode (TRGAN)
