This pin also can be configured as selecting pin which can set the on-chip SPI
interface work under Master mode or Slave mode. To set the SPI interface of this
device work under Slave mode, the user can connect this pin to VSS, or to a CEB
output from other SPI master. To set the SPI interface of this device work under
Master mode, just tie this pin to VDD.
Port 4.3 GPIO
