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 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).
3. When a pin sharing the serial interface IICA function is to be used as a general-purpose port pin, operation
of the corresponding serial interface IICA must be stopped.
4. 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).
5. 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.
6. Functions in parentheses can be assigned via settings in the peripheral I/O redirection registers 1, 3, 4, 6
(PIOR1, PIOR3, PIOR4, PIOR6).
Remark ï‚´: Don't care
PM6x: Port mode register 6
PIM6x: Port input mode register 6
POM6x: Port output mode register 6
PITHL6x: Port input threshold control register 6
