• Manufacturer Part Number: HD6412350
• Description: (HD6412350 / HD6432351) 16-BIT MICROCONTROLLER
• Manufacturer: Hitachi

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 16 input capture/compare match interrupts, four each for channels 0 and 3, and two each
for channels 1, 2, 4, and 5.
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 TPU has six 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 a channel. The interrupt
request is cleared by clearing the TCFU flag to 0. The TPU has four underflow interrupts, one
each for channels 1, 2, 4, and 5.
10.5.2
DTC Activation: The DTC can be activated by the TGR input capture/compare match interrupt
for a channel. For details, see section 8, Data Transfer Controller.
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.
DMAC Activation: The DMAC can be activated by the TGRA input capture/compare match
interrupt for a channel. For details, see section 7, DMA Controller.
In the TPU, a total of six TGRA input capture/compare match interrupts can be used as DMAC
activation sources, one for each channel.
10.5.3
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 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.
