Slave
Ground
Slave Domain Ground Connection. This pin can be left unconnected.
5
SGND1
Slave
Ground
Slave Domain SPI Isolator Ground.
6
SSS
Slave
Output
SPI Slave Select Output. This pin is paired with MSS. On the master domain, MSS
drives this pin.
7
SO
Slave
Input
SPI Data Input Going to the Master MI and SO Line. This pin is paired with MI. On
the master domain, this pin drives MI.
8
SI
Slave
Output
SPI Data Output from the Master MO and SI Line. This pin is paired with MO. On
the master domain, MO drives this pin.
9
SCK
Slave
Output
