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 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).
3. 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).
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. When a pin sharing the STOP status output function is to be used as a general-purpose port pin, the
STPOEN bit of the STOP status output control register (STPSTC) must have the same setting as its initial
value.
6. Functions in parentheses can be assigned via settings in the peripheral I/O redirection registers 3, 4, 6
(PIOR3, PIOR4, PIOR6). The STOPST function can be assigned via settings in the STOP status output
control register (STPSTC).
Remark ï‚´: Don't care
PM5x: Port mode register 5
PIM5x: Port input mode register 5
PITHL5x: Port input threshold control register 5
