Notes 1. When a pin sharing a timer RD function is to be used as a general-purpose port pin, the target bit for

TRDIOij pin output control in the timer RD output master enable register 1 (TRDOER1) must have the

same setting as its initial value (i = A, B, C, D, j = 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

state (m = 0, 1, n = 0 to 7).

3. 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).

4. 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.

5. Functions in parentheses can be assigned via settings in the peripheral I/O redirection register 1 (PIOR1).

Caution The function setting on P121 to P124 is available only once after the reset release. The port once set

for connection to a resonator or an oscillator cannot be used as an input port unless the reset is
