(b)
Single-Chip Mode and Address-Data Multiplex Extended Mode
Port A pins can also function as interrupt input, EtherC control input/output, and event counter
input pins.
•
PA7/
ExIRQ7
/EVENT7/EXOUT
The pin function is switched as shown below according to the PA7DDR bit.
Setting the ISS7 bit in ISSR makes the pin to function as the
ExIRQ7
input pin.
When using this pin as the
ExIRQ7
input or EVENT7 input pin, clear the PA7DDR bit to 0.
Though the settings for the EVENT input pin have been made, set the PA7DDR bit to 1 to use
the pin as the PA7 output pin.
When the module stop mode is cleared in both the EtherC and E-DMAC, this pin functions as
the EXOUT output pin.

PA6/
ExIRQ6
/EVENT6/LNKSTA
The pin function is switched as shown below according to the PA6DDR bit.
Setting the ISS6 bit in ISSR makes the pin to function as the
ExIRQ6
input pin.
When using this pin as the
ExIRQ6
input, or EVENT6 input pin, clear the PA6DDR bit to 0.
Though the settings for the EVENT input pin have been made, set the PA6DDR bit to 1 to use
the pin as the PA6 output pin.
When the module stop mode is cleared in both the EtherC and E-DMAC, this pin functions as
the LNKSTA input pin.
