All
the KSZ8895MQX/RQX/FQX/MLX 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.
Serial bus configuration pin.
For this case, if the EEPROM is not present, the KSZ8895MQX/
RQX/FQX/MLX will start itself with the PS [1:0] = 00 default register
values.
