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
H8S/2268 Group TPU has eight input capture/compare match interrupts and the H8S/2264 Group
TPU has four input capture/compare match interrupts, four for channel 0, and two each for
channels 1 and 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 H8S/2268 Group TPU has three overflow
interrupts and the H8S/2264 Group TPU has two overflow interrupts, one for each channel
(channels 0 to 2, or 1 and 2).
Underflow Interrupt (H8S/2268 Group Only): 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 TPU has two
underflow interrupts, one each for channels 1 and 2.
10.7
The DTC can be activated by the TGR input capture/compare match interrupt for a channel. For
details, see section 8, Data Transfer Controller (DTC).
A total of eight TPU input capture/compare match interrupts can be used as DTC activation
sources, four for channel 0, and two each for channels 1 and 2.
10.8
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 begin 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 begun.
In the H8S/2268 Group TPU, a total of three TGRA input capture/compare match interrupts can
be used as A/D converter conversion start sources, one for each channel (channels 0 to 2). While
in the H8S/2264 Group TPU, a total of two TGRA input capture/compare match interrupts can be
used, one for each channel (channels 1 and 2).
