Description
Serial bus configuration pins to select mode of access to
KSZ8993M internal registers.
[PS1, PS0] = [0, 0] — I
(If EEPROM is not detected, the power-up default values of
the KSZ8993M internal registers will be used.)
[PS1, PS0] = [0, 1] — I
The external I
The KSZ8993M device addresses are:
1011_1111
1011_1110
[PS1, PS0] = [1, 0] — SPI slave mode
[PS1, PS0] = [1, 1] – SMI-mode
In this mode, the KSZ8993M provides access to all its internal
8 bit registers through its MDC and MDIO pins.
Note:
When (PS1, PS0) ≠ (1,1), the KSZ8993M provides access to
its 16 bit MIIM registers through its MDC and MDIO pins.
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
I/O = Bi-directional.
