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 I
mode. See “Pin 113.”
(1) Input clock up to 5MHz in SPI slave mode; (2) output clock at
81kHz in I
(1) Serial data input in SPI slave mode; (2) serial data input/output in
I
Active low. (1) SPI data transfer start in SPI slave mode. When SPIS_N
is high, the KS8995MA 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 I
Serial bus configuration pin.
For this case, if the EEPROM is not present, the KS8995MA will start
itself with the PS[1:0] = 00 default register values .
