Pin function
When the PW7S bit in PTCNT0 is set to 1, this pin can be used as the ExPW7 pin.
According to the combination of the C/A bit in SMR of the SCI_4, the CKE0 and CKE1 bits in
SCR, the OS3 to OS0 bits in TCSR of the TMRY_0, the OE7 bit in PWOER of the PWM, the
PW7S bit, and the PA1DDR bit, the pin function is switched as shown below.
When the PW6S bit in PTCNT0 is set to 1, this pin can be used as the ExPW6 pin.
According to the combination of the C/A bit in SMR of the SCI_3, the CKE0 and CKE1 bits in
SCR, the OS3 to OS0 bits in TCSR of the TMRX_0, the OE6 bit in PWOER of the PWM, the
PW6S bit, and the PA0DDR bit, the pin function is switched as shown below.
