the interrupt functionality. When the Nexus Secondary Port is selected and active, this pin is used as an

Event In input.

PC[4] / ADDR[4] / NEX2MCKO — Port C I/O Pins, External Address

Bus and Nexus Secondary

PC[4] is a configurable general purpose input or output pin. It can be independently configured to provide

either high or reduced output drive, and also to enable or disable either a pull-up or pull-down resistor on

the pin. The pin is multiplexed with the external address bus line Address 3. Each pin can be independently

configured to wake the system out of low-power mode (DOZE) when an external signal is applied using

the interrupt functionality. When the Nexus Secondary Port is selected and active, this pin is used as a

Message Clock output.

PC[5] / ADDR[5] / NEX2EVTO — Port C I/O Pins, External Address

Bus and Nexus Secondary

PC[5] is a configurable general purpose input or output pin. It can be independently configured to provide

either high or reduced output drive, and also to enable or disable either a pull-up or pull-down resistor on

the pin. The pin is multiplexed with the external address bus line Address 3. Each pin can be independently

configured to wake the system out of low-power mode (DOZE) when an external signal is applied using

the interrupt functionality. When the Nexus Secondary Port is selected and active, this pin is used as a

Event Out output.

4.3.31

PC[6] / ADDR[6] / NEX2MSEO — Port C I/O Pins, External Address

Bus and Nexus Secondary

PC[6] is a configurable general purpose input or output pin. It can be independently configured to provide

either high or reduced output drive, and also to enable or disable either a pull-up or pull-down resistor on

the pin. The pin is multiplexed with the external address bus line Address 3. Each pin can be independently

configured to wake the system out of low-power mode (DOZE) when an external signal is applied using

the interrupt functionality. When the Nexus Secondary Port is selected and active, this pin is used as a

Message Start/End output.

4.3.32

PC[7] / ADDR[7] / NEX2RDY — Port C I/O Pins, External Address Bus

and Nexus Secondary

PC[7] is a configurable general purpose input or output pin. It can be independently configured to provide

either high or reduced output drive, and also to enable or disable either a pull-up or pull-down resistor on

the pin. The pin is multiplexed with the external address bus line Address 3. Each pin can be independently

configured to wake the system out of low-power mode (DOZE) when an external signal is applied using

the interrupt functionality. When the Nexus Secondary Port is selected and active, this pin is used as a

Nexus Ready output.
