DTC Activation

The DTC can be activated by the TGR input capture/compare match interrupt for a channel. For

details, see section 12, Data Transfer Controller (DTC).

A total of 16 TPU input capture/compare match interrupts can be used as DTC activation sources,

four each for channels 0 and 3, and two each for channels 1, 2, 4, and 5.

14.7

DMAC Activation

The DMAC can be activated by the TGRA input capture/compare match interrupt for a channel.

For details, see section 10, DMA Controller (DMAC).

In TPU, one in each channel, totally six TGRA input capture/compare match interrupts can be

used as DMAC activation sources.

14.8

A/D Converter Activation

Concerning the unit 0 in TPU, the TGRA input capture/compare match for each channel can

activate the A/D converter. (However, the A/D converter cannot be activated in 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.
