(4) Pin Functions
Port F is a 3-bit I/O port. Port F pins can also function as PWMX output pins and EtherC control
I/O 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, 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.
• PF1/RS9/MDC
The pin function is switched as shown below according to the combination of the module stop
state in the EtherC and e-DMAC and the PF1DDR bit.
EtherC, E-DMAC Either of them is stopped Both of them are stopped
PF1DDR 0 1 X
Pin function PF1 input pin PF1 output pin MDC output pin
[Legend] X: Don't care.
• PF0/RS0/MDIO
The pin function is switched as shown below according to the combination of the module stop
state in the EtherC and e-DMAC and the PF0DDR bit.
EtherC, E-DMAC Either of them is stopped Both of them are stopped
PF0DDR 0 1 X
Pin function PF0 input pin PF0 output pin MDIO input/output pin
[Legend] X: Don't care.
