(4) Pin Functions
Port F is a 7-bit I/O port. Port F pins can also function as the PWM output and EtherC control
input/output pins. The relationship between the register settings and the pin function is shown
below.
• PF6/ExPWX2/RS14
The pin function is switched as shown below according to the combination of the OEA bit in
DACR and the PWMXS bit in PTCNT0 of PWMX_1 and the PF6DDR bit.
PF6DDR 0 1 X
PWMXS 0 1 0 1 1
OEA X 0 X 0 1
Pin function PF6 input pin PF6 output pin ExPWX2 output pin
[Legend] X: Don't care.
• PF5/RS13
The pin function is switched as shown below according to the PF5DDR bit.
PF5DDR 0 1
Pin function PF5 input pin PF5 output pin
• PF4/RS12
The pin function is switched as shown below according to the PF4DDR bit.
PF4DDR 0 1
Pin function PF4 input pin PF4 output pin
• PF3/ExPWX3/RS11
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 PF3DDR bit.
PF3DDR 0 1 X
PWMXS 0 1 0 1 1
OEA X 0 X 0 1
Pin function PF3 input pin PF3 output pin ExPWX3 output pin
[Legend] X: Don't care.
