Section 10 16-Bit Timer Pulse Unit (TPU)
Contention between TCNT Write and Overflow/Underflow: If there is an up-count or down-
count in the T
precedence and the TCFV/TCFU flag in TSR is not set.
Figure 10.57 shows the operation timing when there is contention between TCNT write and
overflow.
Multiplexing of I/O Pins: In the chip, the TCLKA input pin is multiplexed with the TIOCC0 I/O
pin, the TCLKB input pin with the TIOCD0 I/O pin, the TCLKC input pin with the TIOCB1 I/O
pin, and the TCLKD input pin with the TIOCB2 I/O pin. When an external clock is input,
compare match output should not be performed from a multiplexed pin.
Interrupts and Module Stop Mode: If module stop mode is entered when an interrupt has been
requested, it will not be possible to clear the CPU interrupt source or the DMAC * or DTC
activation source. Interrupts should therefore be disabled before entering module stop mode.
Note: * The DMAC is not supported in the H8S/2321.
