Port F

(1) PF7/PWMU5A, PF6/PWMU4A, PF5/PWMU3A, PF4/PWMU2A
The pin function is switched as shown below according to the combination of the PWMmE bit in
PWMOUTCR of PWMU_A and the PFnDDR bit.
PFnDDR
PWMmE
Pin function
(2) PF3/TMOX/IRQ11
The pin function is switched as shown below according to the combination of the OS3 to OS0 bits
in TCSR of TMR_X and the PF3DDR bit.
When the ISS11 bit in ISSR16 is cleared to 0 and the IRQ11E bit in IER16 of the interrupt
controller is set to 1, this functions as the IRQ11 input pin.
OS3 to OS0
PF3DDR
Pin function
(3) PF2/TMOY/IRQ10
The pin function is switched as shown below according to the combination of the OS3 to OS0 bits
in TCSR of TMR_Y and the PF2DDR bit.
When the ISS10 bit in ISSR16 is cleared to 0 and the IRQ10E bit in IER16 of the interrupt
controller is set to 1, this pin functions as the IRQ10 input pin.
OS3 to OS0
PF2DDR
Pin function
