Notes 1. 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).
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 timer output function of the timer RJ is to be used as a general-purpose port pin,
the bit 2 (TOENA) of the timer RJ I/O control register 0 (TRJIOC0) 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 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).
5. 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)
6. The RCLOE1 bit of the real-time clock control register 0 (RTCC0) must have the same setting as its initial
value.
7. 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.
8. When a pin sharing the serial data output function of the LIN is to be used as a general-purpose port pin,
operation of the corresponding LIN must be stopped.
9. 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.
10. When the SNOOZE status output is in use, output from TRDIOC0 is stopped.
11. Functions in parentheses can be assigned via settings in the peripheral I/O redirection register 7 (PIOR7).
