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, the TCLKD input pin
with the TIOCB2 I/O pin, the TCLKE input pin with the TIOCC6 I/O pin, the TCLKF input pin
with the TIOCD6 I/O pin, the TCLKG input pin with the TIOCB7 I/O pin, and the TCLKH input
pin with the TIOCB8 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 a transition is made to the module stop state 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 the module stop state.
