Section 9 16-Bit Timer Pulse Unit (TPU)
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
TPU has 8 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 particular channel. The
interrupt request is cleared by clearing the TCFV flag to 0. The TPU has three overflow interrupts,
one for each channel.
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 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.
9.5.2
DTC Activation: The DTC can be activated by the TGR input capture/compare match interrupt
for a channel. For details, see section 7, Data Transfer Controller.
A total of 8 TPU input capture/compare match interrupts can be used as DTC activation sources,
four for channels 0, and two each for channels 1, and 2.
9.5.3
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 TFGA 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 three TGRA input capture/compare match interrupts can be used as A/D
converter conversion start sources, one for each channel.
