(2) A/D Converter Activation by Compare Match between TCNT_0 and TGRE_0
The A/D converter can be activated by generating A/D converter start request signal TRG0N
when a compare match occurs between TCNT_0 and TGRE_0 in channel 0.
When the TGFE flag in TSR2_0 is set to 1 by the occurrence of a compare match between
TCNT_0 and TGRE_0 in channel 0 while the TTGE2 bit in TIER2_0 is set to 1, A/D converter
start request TGR0N is issued to the A/D converter. If A/D converter start signal TGR0N from the
MTU2 is selected as the trigger in the A/D converter, A/D conversion will start.
(3) 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 TCNT_4 count matches the TADCORA or TADCORB value if the TAD4AE
or TAD4BE bit in the A/D converter start request control register (TADCR) is set to 1. For details,
refer to section 12.4.9, A/D Converter Start Request Delaying Function.
A/D conversion will start if A/D converter start signal TRG4AN from the MTU2 is selected as the
trigger in the A/D converter when TRG4AN is generated or if TRG4BN from the MTU2 is
selected as the trigger in the A/D converter when TRG4BN is generated.
