11.8 A/D Converter Activation
The A/D converter can be activated by the TGRA input capture/compare match for a channel.
If the TTGE bit in TIER is set to 1 when the TGFA flag in TSR is set to 1 by the occurrence of a
TGRA input capture/compare match on a particular channel, a request to start A/D conversion is
sent to the A/D converter. If the TPU conversion start trigger has been selected on the A/D
converter side at this time, A/D conversion is started.
In the TPU, a total of six TGRA input capture/compare match interrupts can be used as A/D
converter conversion start sources, one for each channel.
