MDC
Ipu
All
Switch or PHY[5] MII management data clock.
108
MDIO
I/O
All
Switch or PHY[5] MII management data I/O.
Features internal pull down to define pin state when not driven.
109
SPIQ
Otri
All
(1) SPI serial data output in SPI slave mode; (2) output clock at 61kHz in I2C master
mode. See “Pin 113.”
110
SPIC/SCL
I/O
All
(1) Input clock up to 5MHz in SPI slave mode; (2) output clock at 61kHz in I2C master
mode. See “Pin 113.”
111
SSPID/SDA
I/O
All
(1) Serial data input in SPI slave mode; (2) serial data input/output in I2C master
mode. See “Pin 113.”
112
SPIS_N
Ipu
All
Active low. (1) SPI data transfer start in SPI slave mode. When SPIS_N is high, the
KS8995MA/FQ is deselected and SPIQ is held in high impedance state, a high-to-low
transition to initiate the SPI data transfer; (2) not used in I2C master mode.
113
PS1
Ipd
Serial bus configuration pin. For this case, if the EEPROM is not present, the
KS8995MA/FQ will start itself with the PS[1.0] = 00 default register values.
Pin Configuration

P = Power supply.
I = Input.
O = Output.
I/O = Bidirectional.
GND = Ground.
Ipu = Input w/internal pull-up.
Ipd = Input w/internal pull-down.
Ipd/O = Input w/internal pull-down during reset, output pin otherwise.
Ipu/O = Input w/internal pull-up during reset, output pin otherwise.
NC = No connect.
