7.2.8 Port
8
(1) P86/
IRQ5
/SCK1/SCL1
The pin function is switched as shown below according to the combination of the C/
A
bit in SMR
of SCI_1, CKE0 and CKE1 bits in SCR, IIC1AS and IIC1BS bits in PTCNT1, ICE bit in ICCR of
IIC_1, and the P86DDR bit. When the ISS5 bit in ISSR is cleared to 0 and the IRQ5E bit in IER of
the interrupt controller is set to 1, this pin can be used as the
IRQ5
input pin.

Note: To use this pin as SCL1 input/output, be sure that SCK1_OE is 0. To use this pin as SCL1,
the IIC1AS and IIC1BS bits in PTCNT1 must be cleared to 0. The output format for SCL1 is
NMOS output only and direct bus drive is possible. When this pin is used as the P86 output
pin or SCK1 output pin, the output format is NMOS push-pull.
(2) P85/

/RxD1
The pin function is switched as shown below according to the state of the P85DDR bit.
