Note
Set together with bits 0 and 1 of the PRM10 register. (See
Figure 7-7
)
Cautions 1. When selecting the valid edge of TI1n as the count clock, do not specify the valid edge of
TI1n to clear and start the timer and as a capture trigger.
2. Before setting data to PRM1n, always stop the timer operation.
3. If the 16-bit timer (TM1) operation is enabled by specifying the rising edge or both edges
for the valid edge of the TI1n pin while the TI1n pin is high level immediately after system
reset, the rising edge is detected immediately after the rising edge or both edges is
specified. Be careful when pulling up TI1n pin. However, the rising edge is not detected
when operation is enabled after it has been stopped.
