/EVENT5/WOL
The pin function is switched as shown below according to the setting of the and the PA5DDR
bit.
Setting the ISS5 bit in ISSR makes the pin to function as the
ExIRQ5
input pin.
When using this pin as the
ExIRQ5
input, or EVENT5 input pin, clear the PA5DDR bit to 0.
Though the settings for the EVENT input pin have been made, set the PA5DDR bit to 1 to use
the pin as the PA5 output pin.
When the module stop mode is cleared in poth the EtherC and E-DMAC, this pin functions as
the WOL input pin.

The pin function is switched as shown below according to the PAnDDR bit.
Setting the ISSn bit in ISSR makes the pin to function as the
ExIRQn
input pin.
When using this pin as the
ExIRQn
input or EVENTn input pin, clear the PAnDDR bit to 0.
Though the settings for the EVENT input pin have been made, set the PAnDDR bit to 1 to use
the pin as the PAn output pin.

Input Pull-Up MOS
Port A has built-in input pull-up MOSs that can be controlled by software. This input pull-up
MOS can be used in any operating mode, and can be specified as on or off on a bit-by-bit basis.
