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

the interrupt functionality.

4.3.58

PF[15] / SIN_C — Port F I/O Pin and DSPI_C

PF[15] is a configurable general purpose input or output pin. It can be configured to provide either high or

reduced output drive, to enable or disable either a pull-up or pull-down resistor on the pin or to provide

either an open drain or push-pull pad. The pin can be configured as the input pin of the Serial Peripheral

Interface C (DSPI_C). It can be configured to wake the system out of low-power mode (DOZE) when an

external signal is applied using the interrupt functionality.

4.3.59

PG[0] / RXD_B — PORT G I/O Pin and ESCI_B

PG[0] is a configurable general purpose input or output pin. The pin can be configured to provide either

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

pin. It is multiplexed with the receive pin for the Enhanced Serial Communications Interface controller B

(ESCI_B). It can be configured to wake the system out of low-power mode (DOZE) when an external

signal is applied using the interrupt functionality.

4.3.60

PG[1] / TXD_B — PORT G I/O Pin and ESCI_B

PG[1] is a configurable general purpose input or output pin. The pin can be configured to provide either

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

pin. It is multiplexed with the transmit pin for the Enhanced Serial Communications Interface controller

B (ESCI_B). It can be configured to wake the system out of low-power mode (DOZE) when an external

signal is applied using the interrupt functionality.

4.3.61

PG[2] / RXD_A / NEX1MDO — PORT G I/O Pin, ESCI_A and Nexus

Primary

PG[2] is a configurable general purpose input or output pin. The pin can be configured to provide either

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

pin. It is multiplexed with the receive pin for the Enhanced Serial Communications Interface controller A

(ESCI_A). It can be configured to wake the system out of low-power mode (DOZE) when an external

signal is applied using the interrupt functionality. When the Nexus Primary Port is selected and active, this

pin is used as a Message Data Out output.

4.3.62

PG[3] / TXD_A / NEX1MDO — PORT G I/O Pin, ESCI_A and Nexus

Primary

PG[3] is a configurable general purpose input or output pin. The pin can be configured to provide either

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

pin. It is multiplexed with the transmit pin for the Enhanced Serial Communications Interface controller

A (ESCI_A). It can be configured to wake the system out of low-power mode (DOZE) when an external
