LTC4332 Is Slave Select (SSx) independent of SCK

Hi,

I would like to use one of the slave select signals as a general purpose digital output (on the slave side) without a SPI data transfer in the same way that the CTRL pin can be used on the LTC4331 (I2C slave extender) LTC4331 DS page 16, Control.

Is this possible?

The LTC4332 data sheet does not seem to indicate if this is possible or not.

Thanks

Mike
