Switch or PHY[5] MII management data clock
Switch or PHY[5] MII management data I/O.
Features internal pull down to define pin state when not driven.
(1) SPI serial data output in SPI slave mode; (2) Not used in I2C master
mode. See “pin# 113.”
(1) Input clock up to 5MHz in SPI slave mode; (2) Output clock at
81KHz in I2C master mode. See “pin# 113.”
(1) Serial data input in SPI slave mode; (2) Serial data input/output in
I2C master mode See “pin# 113.”
Active low. (1) SPI data transfer start in SPI slave mode. When SPIS_N
is high, the KS8995M 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.
