(1)

Input Capture/Compare Match Interrupt

An interrupt is requested if the TGIE bit in TIER is set to 1 when the TGF flag in TSR is set to 1

by the occurrence of a TGR input capture/compare match on a particular channel. The interrupt

request is cleared by clearing the TGF flag to 0. The MTU2 has 21 input capture/compare match

interrupts, six for channel 0, four each for channels 3 and 4, two each for channels 1 and 2, and

three for channel 5. The TGFE_0 and TGFF_0 flags in channel 0 are not set by the occurrence of

an input capture.

(2)

Overflow Interrupt

An interrupt is requested if the TCIEV bit in TIER is set to 1 when the TCFV flag in TSR is set to

1 by the occurrence of TCNT overflow on a channel. The interrupt request is cleared by clearing

the TCFV flag to 0. The MTU2 has five overflow interrupts, one for each channel.

(3)

Underflow Interrupt

An interrupt is requested if the TCIEU bit in TIER is set to 1 when the TCFU flag in TSR is set to

1 by the occurrence of TCNT underflow on a channel. The interrupt request is cleared by clearing

the TCFU flag to 0. The MTU2 has two underflow interrupts, one each for channels 1 and 2.

10.5.2

DMAC Activation

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

For details, see section 9, Direct Memory Access Controller (DMAC).

In the MTU2, a total of five TGRA input capture/compare match interrupts can be used as DMAC

activation sources, one each for channels 0 to 4.
