Pin Function
Switch MII interface configuration
Digital core ground
Unused pin – externally pull down for normal operation
Unused pin – externally pull down for normal operation
MII management interface: data input/output
Note: an external pull-up is needed on this pin when it is in use.
SPI slave mode: serial data output

See description in pins 100 and 101.
Note: an external pull-up is needed on this pin when it is in use.
SPI slave mode: chip select (active low)
When SPIS_N is high, the KSZ8893FQL is deselected and SPIQ is held in high
impedance state.
A high-to-low transition is used to initiate SPI data transfer.
See description in pins 100 and 101.
Note: an external pull-up is needed on this pin when it is in use.
