III PERIPHERAL BLOCK:
Selects the pin to be used for input of an external count clock to the timer.
Write "1": Clock input pin
Write "0": I/O port pin
Read: Valid
Select clock input pins for the timers that are used as an event counter from among P10 through P16,by writing "1" to
In addition to pin selection here, the pin to be used for clock input to the
At cold start, CFP1x is set to "0" (I/O port). At hot start, CFP1x retains its status from prior to the initial reset.
Selects the pin used for clock output.
Write "1": Clock output pin
Write "0": I/O port pin

Read: Valid
For the pin selected from among P10 through P16 for use for external clock input, write "0" to the corresponding I/O control bit to set it to input mode . If the pin is set to output mode, even though its CFP1x may be set to "1", it functions as the output pin of an
At cold start, all IOC1x is set to "0" (input mode). At hot start, IOC1x retains its state from prior to the initial reset.
