• Manufacturer Part Number: r4f2426
• Description: 16-bit Single-chip Microcomputer H8s Family / H8s/2400 Series
• Manufacturer: Renesas Electronics Corporation.

(1)
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 32 input capture/compare match
interrupts, four each for channels 0, 3, 6, and 9, and two each for channels 1, 2, 4, 5, 7, 8, 10, and
11.
(2)
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 12 overflow interrupts, one for each channel.
(3)
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 eight underflow interrupts, one each for channels 1, 2, 4, 5, 7, 8,
10, and 11.
11.6
The DTC can be activated by the TGR input capture/compare match interrupt for a channel. For
details, see section 9, Data Transfer Controller (DTC).
A total of 32 TPU input capture/compare match interrupts can be used as DTC activation sources,
four each for channels 0, 3, 6, and 9, and two each for channels 1, 2, 4, 5, 7, 8, 10, and 11.
11.7
In unit 0 of the TPU, the DMAC can be activated by the TGRA input capture/compare match
interrupt for a channel. For details, see section 7, DMA Controller (DMAC). (The DMAC cannot
be activated by unit 1.)
In unit 0 of the TPU, a total of six TGRA input capture/compare match interrupts can be used as
DMAC activation sources, one for each channel.
