Description
registers.
[PS1, PS0] = [0, 0] --- I2C master (EEPROM) mode
(If EEPROM is not detected, the power up default values of the
KS8993F internal registers will be used)
[PS1, PS0] = [0, 1] --- I2C slave mode
The external I2C master will drive the SCL clock.
The KS8993F device addresses are:
[PS1, PS0] = [1, 0] --- SPI slave mode
[PS1, PS0] = [1, 1] --- SMI mode
In this mode, the KS8993F provides access to all its internal 8 bit
registers thru its MDC and MDIO pins.
Note
Port 3 port based VLAN mask bits. Use to select which ports may
transmit packets received on port 3.
PV31 = 1, port 1 may transmit packets received on port 3.
PV31 = 0, port 1 will not transmit any packets received on port 3.
PV32 = 1, port 2 may transmit packets received on port 3.
PV32 = 0, port 2 will not transmit any packets received on port 3.
Port 2 port based VLAN mask bits. Use to select which ports may
transmit packets received on port 2.
PV21 = 1, port 1 may transmit packets received on port 2.
PV21 = 0, port 1 will not transmit any packets received on port 2.
PV23 = 1, port 3 may transmit packets received on port 2.
PV23 = 0, port 3 will not transmit any packets received on port 2.
