Unused pins – externally pull down for normal operation
MII management interface: clock input
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 / I²C slave mode: clock input
I²C master mode: clock output
See description in pins 100 and 101.
SPI slave mode: serial data input
I²C master/slave mode: serial data input/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 KSZ8893MQL 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.
