Dtc Trigger Sources - Renesas RX100 Series User Manual

RX13T Group
(1) Input Capture/Compare Match Interrupt
If the TIER.TGIE bit is set to 1 when a TGR input capture/compare match occurs on a channel, an interrupt is requested.
The MTU has 21 input capture/compare match interrupts (six for MTU0, four each for MTU3 and MTU4, two each for
MTU1 and MTU2, and three for MTU5).
(2) Overflow Interrupt
If the TIER.TCIEV bit is set to 1 when a TCNT overflow occurs on a channel, an interrupt is requested. The MTU has
five overflow interrupts (one for each channel except MTU5).
Note that an overflow interrupt is generated also when an underflow of the MTU4.TCNT occurs while operating in
complementary PWM mode.
(3) Underflow Interrupt
If the TIER.TCIEU bit is set to 1 when a TCNT underflow occurs on a channel, an interrupt is requested. The MTU has
two underflow interrupts (one each for MTU1, and MTU2).

DTC Trigger Sources

(1) DTC Trigger Sources
The DTC can be triggered by the TGR input capture/compare match interrupt in each channel or the overflow interrupt in
MTU4. For details, refer to section 16, Data Transfer Controller (DTCb) .
The MTU provides a total of 20 input capture/compare match interrupts and overflow interrupts that can be used as DTC
trigger sources: four each for MTU0 and MTU3, two each for MTU1 and MTU2, five for MTU4, and three for MTU5.
