Pin Function
P86/IRQ5/ SCK1/SCL1
The pin function is switched as shown below according to the combination of the CKE1 and
CKE0 bits in SCR of SCI_1, the C/A bit in SMR of SCI_1, the ICE bit in ICCR of IIC_1, and
the P86DDR bit.
* 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 SCI_1 and bit C/A in
SMR of SCI_1 must all be cleared to 0. When the P86 output pin and SCK1 output pin
are set, the output type is NMOS push-pull output. SCL1 is an NMOS-only output, and
has direct bus drive capability.

The initial value must not be changed.
If a port 8 read is performed while P8DDR bits are
set to 1, the P8DR values are read directly,
regardless of the actual pin states. If a port 8 read
is performed while P8DDR bits are cleared to 0,
the pin states are read.
