Table 8.19 Port 8 Pin Functions
Pin

SCL1
P85/IRQ4/RxD1
P84/IRQ3/TxD1
Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
bits CKE1 and CKE0 in SCR of SCI1, bit C/A in SMR of SCI1, bit ICE in ICCR
of IIC1, and bit P86DDR.
When the IRQ5E bit in IER is set to 1, this pin is used as the IRQ5 input pin.
When this pin is used as the SCL1 I/O pin, bits CKE1 and CKE0 in SCR of
SCI1 and bit C/A in SMR of SCI1 must all be cleared to 0. SCL1 is an NMOS-
only output, and has direct bus drive capability.
The pin function is switched as shown below according to the combination of
bit RE in SCR of SCI1 and bit P85DDR.
When the IRQ4E bit in IER is set to 1, this pin is used as the IRQ4 input pin.
The pin function is switched as shown below according to the combination of
bit TE in SCR of SCI1 and bit P84DDR.
When the IRQ3E bit in IER is set to 1, this pin is used as the IRQ3 input pin.
