Description
MTR0 Multicast Table 3
When the appropriate bit is set, if the packet received with DA matches the CRC, the
hashing function is received without being filtered.
When the appropriate bit is cleared, the packet will drop.
Note: When the receive all (RXRA) or receive multicast (RXRM) bit is set in the RXCR,
all multicast addresses are received regardless of the multicast table value.
Description
Family ID
Chip family ID
Chip ID
0x0 is assigned to KSZ8842M
Revision ID
Start Switch
1 = start the chip.
0 = switch is disabled.
Description
Pass All Frames
1 = switch all packets including bad ones. Used solely for debugging purposes. Works
in conjunction with Sniffer mode only.
Reserved
IEEE 802.3x Transmit Direction Flow Control Enable
1 = enables transmit direction flow control feature.
0 = will not enable transmit direction flow control feature. The switch will not generate
any flow control packets.
IEEE 802.3x Receive Direction Flow Control Enable
1 = enables receive direction flow control feature.
0 = will not enable receive direction flow control feature. The switch will not react to
any received flow control packets.
Frame Length Field Check
1 = checks frame length field in the IEEE packets. If the actual length does not match,
the packet will be dropped (for Length/Type field < 1500).
