In extended mode:
Operation is not affected.
In single-chip mode:
When the pins are in input state, the
corresponding input pull-up MOS is turned on
when a P3PCR bit is set to 1.

Pin Functions
The relationship between register setting values and pin functions are as follows in each operating
mode. Note that MMC mode stands for MultiMediaCard mode, and the symbol “—” stands for
Don't care in the tables.
Extended Mode:
Port 3 pins automatically function as the data bus.
Single-Chip Mode:
•
P37/
WUE15
The pin function is switched as shown below according to the P37DDR bit.
When the WUEM15 bit in WUEMR3 of the interrupt controller is cleared to 0, this pin can be
used as the
WUE15
input pin. To use this pin as the
WUE15
input pin, clear the P37DDR bit
to 0.
