Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
bits OS3 to OS0 in TCSR of TMR0, bit RE in SCR of SCI2 and bit P41DDR.
When this pin is used as the TMO0 output pin, bit RE in SCR of SCI2 must be
cleared to 0.
The pin function is switched as shown below according to the combination of
bit TE in SCR of SCI2 and bit P40DDR.
When an external clock is selected with bits CKS2 to CKS0 in TCR0 of TMR0,
this pin is used as the TMCI0 input pin.
