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.

• 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.
