• P65/ExIRQ10/RTS
The pin function is switched as shown below according to the combination of the
enable/disable setting of the SCIF and the P65DDR bit.
When the ISS10 bit in ISSR16 is set to 1, this pin can be used as the ExIRQ10 input pin. To
use as the ExIRQ10 input pin, clear the P65DDR bit to 0.
SCIF Disabled Enabled
P65DDR 0 1 X
P65 input pin Pin function
IRQ10 input pin
P65 output pin RTS output pin
[Legend] X: Don't care.
• P64/ExIRQ11/CTS
The pin function is switched as shown below according to the combination of the
enable/disable setting of the SCIF and the P64DDR bit.
When the ISS10 bit in ISSR16 is set to 1, this pin can be used as the ExIRQ11 input pin. To
use as the ExIRQ11 input pin, clear the P64DDR bit to 0.
SCIF Disabled Enabled

[Legend] X: Don't care.
• P63/PWX3
The pin function is switched as shown below according to the combination of the OEB bit in
DACR and the PWMXS bit in PTCNT0 of PWMX_1 and the P63DDR bit.
P63DDR 0 1 X
PWMXS 0 1 0 1 0
OEB 0 X 0 X 1
