(2) A/D Converter Activation by Compare Match between MTU0.TCNT and MTU0.TGRE
A compare match between the MTU0.TCNT counter and the MTU0.TGRE register activates the A/D converter.
A/D converter start request signal TRG0EN is issued when a compare match occurs between the MTU0.TCNT counter
and the MTU0.TGRE register. If A/D converter start signal TRG0EN from the MTU is selected as the trigger in the A/D
converter, A/D conversion will start.
(3) A/D Converter Activation by Compare Match between MTU0.TCNT and MTU0.TGRF
An input capture or compare match between the MTU0.TCNT counter and the MTU0.TGRA or MTU0.TGRB register
activates the A/D converter.
A compare match between the MTU0.TCNT counter and the MTU0.TGRF register activates the A/D converter.
A/D converter start request signal TRG0FN is issued when a compare match occurs between the MTU0.TCNT counter
and the MTU0.TGRF register. If A/D converter start signal TRG0FN from the MTU is selected as the trigger in the A/D
converter, A/D conversion will start.
(4) A/D Converter Activation by Input Capture or Compare Match with MTU0.TGRA or TGRB
The A/D converter can be activated when an input capture or compare match occurs between the MTU0.TCNT counter
and the MTU0.TGRA or MTU0.TGRB register.
When an input capture or compare match occurs between the MTU0.TCNT counter and the MTU0.TGRA or
MTU0.TGRB register. A/D converter start request signal TRG0AN or TRG0BN is issued. If A/D converter start signal
TRG0AN or TRG0BN from the MTU is selected as the trigger in the A/D converter, A/D conversion will start.
(5) A/D Converter Activation by A/D Converter Start Request Delaying Function
The A/D converter can be activated by generating A/D converter start request signal TRG4AN or TRG4BN when the
MTU4.TCNT count matches the TADCORA or TADCORB register value if the TADCR.UT4AE bit, TADCR.DT4AE
bit, TADCR.UT4BE bit, or TADCR.DT4BE bit is set to 1. For details, refer to
section 23.3.9, A/D Converter Start
A/D conversion will start if A/D converter start signal TRG4ABN from the MTU is selected as the trigger in the A/D
converter when TRG4AN or TRG4BN is generated.
