Pin Functions

The relationship between register setting values and pin functions is as follows.
• P67/RxD2/D7
The pin function is switched as shown below according to the combination of the operating
mode, the RE bit in SCR of the SCI_2, and the P67DDR bit.
• Extended Mode (EXPE = 1)

Description
•
In normal extended mode (16-bit data bus)
Operation is not affected.
•
In normal extended mode (8-bit data
bus)/multiplex extended mode
Operates as single-chip mode
•
In single-chip mode
When the pins are in the input states, the
corresponding input pull-up MOS is turned on
when a P6PCR bit is set to 1.
Description
Setting a bit to 1 specifies the PMOS of the
corresponding pin to the off state. When a pin function
is specified as an output port, open-drain output is
enabled. Push-pull output is enabled when a pin
cleared to 0 is specified as an output port.
