Bank 32 Switch Global Control Register 3 (0x06): SGCR3
This register contains the global control for the switch function.

Description
15-8
0x63
RW
Broadcast Storm Protection Rate Bit [7:0]
These bits, along with SGCR3[2:0], determine how many 64-byte blocks of packet
data are allowed on an input port in a preset period. The period is 67ms for 100BT or
670ms for 10BT. The default is 1%.

0
RW
Repeater Mode (Note 1)
1 = enable repeater mode.
0 = normal mode.
The switch supports only half duplex , 100BT in repeater mode.
6
0
RW
Switch Host Half-Duplex Mode
The KSZ8842M supports only half-duplex 100-BaseT throughput in repeater mode.
1 = enable host port interface half-duplex mode, this bit must be set for repeater mode
0 = enable host port interface full-duplex mode..
5
0
RW
Switch Flow Control Enable
1 = enable full-duplex flow control on Switch Host port.
0 = disable full-duplex flow control on Switch Host port

RW
Null VID Replacement
1 = replaces NULL VID with port VID(12 bits).
0 = no replacement for NULL VID.

0x0
RW
Broadcast Storm Protection Rate Bit [10:8]
These bits, along with SGCR3[15:8] determine how many 64-byte blocks of packet
data are allowed on an input port in a preset period. The period is 67ms for 100BT or
670ms for 10BT. The default is 1%.
Rate: 148,800 frames/sec * 67 ms/interval * 1% = 99 frames/interval (approx.) = 0x63.
Note 1: User has to set bit 13 (100Mbps), bit 12 (auto-negotiation disabled) and bit 8 (half duplex) in both P1MBCR and
P2MBCR registers for repeater mode.
