Section 11 16-Bit Timer Pulse Unit (TPU)
11.10.12 Contention between TCNT Write and Overflow/Underflow
If there is an up-count or down-count in the T
overflow/underflow occurs, the TCNT write takes precedence and the TCFV/TCFU flag in TSR is
not set.
Figure 11.54 shows the operation timing when there is contention between TCNT write and
overflow.
11.10.13 Multiplexing of I/O Pins
In this LSI, 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.
11.10.14 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: * Supported only by the H8S/2239 Group.
