Notes 1. When a pin sharing the serial array unit function is to be used as a general-purpose port pin, the SOmn bit
of the serial output register m (SOm), the SOEmn bit of the serial output enable register m (SOEm), and
the SEmn bit of the serial channel enable status register m (SEm) corresponding to the target unit and
channel must have the same setting as its initial value (m = 0, 1, n = 0, 1).
2. When a pin sharing a timer output function of the timer array unit is to be used as a general-purpose port
pin, the TOmn bit of the timer output register m (TOm) and the TOEmn bit of the timer output enable
register m (TOEm) corresponding to the target unit and channel must have the same setting as in the initial
state (m = 0, 1, n = 0 to 7).
3. When a pin sharing the SNOOZE status output function is to be used as a general-purpose port pin, the
OUTEN0 to OUTEN7 bits of the SNOOZE status output control registers 0, 1, 2, 3 (PSNZCNT0, 1, 2, 3)
must have the same setting as its initial value.
4. When a pin sharing the serial array unit function is to be used as a general-purpose port pin, the CKOmn
bit of the serial output register m (SOm), the SOEmn bit of the serial output enable register m (SOEm), and
the SEmn bit of the serial channel enable status register m (SEm) corresponding to the target unit and
channel must have the same setting as its initial value (m = 0, 1, n = 0, 1).
5. When a pin sharing the serial data output function of the CAN is to be used as a general-purpose port pin,
operation of the corresponding CAN must be stopped.
6. Functions in parentheses can be assigned via settings in the peripheral I/O redirection register 4 (PIOR4).
