Description
MTR0 Multicast Table 1
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
MTR0 Multicast Table 2
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
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
PME_Status
This bit indicates that the KSZ8841M has detected a power-management event. If bit
PME_Enable is set, the KSZ8841M also asserts the PMEN pin. This bit is cleared on power-
up reset or by write 1. It is not modified by either hardware or software reset. When this bit is
cleared, the KSZ8841M deasserts the PMEN pin.
Reserved.
PME_Enable
If this bit is set, the KSZ8841M can assert the PMEN pin. Otherwise, assertion of the PMEN
pin is disabled.
This bit is cleared on power-up reset and will be not modified by software reset.
Reserved.
