Ipd
Priority select. Select queue servicing if using split queues.
Use the table below to select the desired servicing. Note that
this selection effects all split transmit queue ports in the same
way.
(PRSEL1, PRSEL0)
Description
(0,0)
Transmit all high priority before low
priority
(0,1)
Transmit high priority and low priority at
10:1 ratio.
(1,0)
Transmit high priority and low priority at
5:1 ratio.
(1,1)
Transmit high priority and low priority at
2:1 ratio.

MDIO
Ipu/O
MII management interface: data input/output
Note: an external 4.7K pull-up is needed on this pin when it is
in use.

SPIQ
Opu
SPI slave mode: serial data output
See description in pins 100 and 101.
97
SCL
Ipu/O
SPI slave mode / I

C slave mode: clock input
I
2C master mode: clock output
See description in pins 100 and 101.
98
SDA
Ipu/O
SPI slave mode: serial data input
I
2C master/slave mode: serial data input/output
See description in pins 100 and 101.

SPIS_N
Ipu
SPI slave mode: chip select (active low)
When SPIS_N is high, the KS8993M 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:
1. P = Power supply.
Gnd = Ground.
Ipu = Input w/ internal pull-up.
Ipd = Input w/ internal pull-down.
Ipu/O = Input w/ internal pull-up during reset, output pin otherwise.
Opu = Output w/ internal pull-up.
