DMAC Activation

The DMAC can be activated by the TGR input capture/compare match interrupt for a channel. For
details, see section 7, DMA Controller (DMAC).
A total of six TPU input capture/compare match interrupts can be used as DMAC activation
sources, one for each channel.

A/D Converter Activation

The TGRA input capture/compare match for each channel of unit 0 can activate the A/D converter
(this function is not available for unit 1).
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.
The A/D converter cannot be activated by unit 1.
