MSP430F2012: MSP430F2012 in 4 pin SPI mode

Part Number:MSP430F2012

Hi,

I intend to use a small MSP430F2012 to read out a DC potmeter value and transmit that over a SPI in slave mode.

Since I have one SPI master and a total of four SPI slaves in my system I want to use the STE pin to disable the MSP430F2012 when the other SPI slaves are addressed.

The MSP430Fx2xx Family Users guide indicates 4 pin SPI mode is possible on the MSP430F2012 but the datasheet doesn't show the STE pin availability.

Can you explain if 4 pin SPI slave mode is possible on the MSP430F2012 or not and if so, which pin is assigned to the SPI-STE pin.

Regards.
