Pin Function
P52/SCK0/SCL0
The pin function is switched as shown below according to the combination of the CKE1 and
CKE0 bits in SCR of SCI_0, the C/A bit in SMR of SCI_0, the ICE bit in ICCR of IIC_0, and
the P52DDR bit.
in SMR of SCI0 must all be cleared to 0.
SCL0 is an NMOS open-drain output, and has direct bus drive capability.
When set as the P52 output pin or SCK0 output pin, this pin is an NMOS push-pull output.

Description
Reserved
The initial value must not be changed.
If a port 5 read is performed while P5DDR bits are
set to 1, the P5DR values are read directly,
regardless of the actual pin states. If a port 5 read
is performed while P5DDR bits are cleared to 0,
the pin states are read.
