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

Interface A (DSPI_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 the Nexus Message Start/End output.

PB[3] / SOUT_A / NEX1RDY — Port B I/O Pin, DSPI_A and Nexus

Primary

PB[3] 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 output pin of the Serial Peripheral

Interface A (DSPI_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 the Nexus Ready output.

4.3.16

PB[4] / SCK_A — Port B I/O Pin and DSPI_A

PB[4] 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 serial clock pin SCK of the Serial

Peripheral Interface A (DSPI_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.

4.3.17

PB[5] / PCS[0] / SS[0] — Port B I/O Pin and DSPI_A

PB[5] 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 chip select pin PCS[0] when in Master

mode, or as slave select pin SS when in Slave mode for the Serial Peripheral Interface A (DSPI_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.

4.3.18

PB[6:7] / PCS[1:2] — Port B I/O Pin and DSPI_A

PB[6] - PB[7] are configurable general purpose input or output pins. They can be configured to provide

either high or reduced output drives, to enable or disable either a pull-up or pull-down resistor on the pins

or to provide either open drain or push-pull pads. The pins can be configured as chip select pin PCS[1:2]

when in Master mode for the Serial Peripheral Interface A (DSPI_A). 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.

4.3.19

PB[8] / PCS[5] / PCSS — Port B I/O Pin and DSPI_A

PB[8] 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
