MAC Additional Station Address Low Register (MAAL0-15)
The KSZ8842-PMQL/PMBL supports 16 additional MAC addresses for MAC address filtering. This MAC address is
used to define one of the 16 destination addresses that the KSZ8842-PMQL/PMBL will respond to when receiving
frames on the port. Network addresses are generally expressed in the form of 01:23:45:67:89:AB, where the bytes are
received left to right, and the bits within each byte are received right to left (LSB to MSB). The actual transmitted and
received bits are in the order of 10000000 11000100 10100010 11100110 10010001 11010101.
The following table shows the register bit fields.
MAC Additional Station Address High Register (MAAH0-15)
The KSZ8842-PMQL/PMBL supports 16 additional MAC addresses for MAC address filtering. This MAC address is
used to define one of the 16 destination addresses that the KSZ8842-PMQL/PMBL will respond to when receiving
frames on the host port. Network addresses are generally expressed in the form of 01:23:45:67:89:AB, where the bytes
are received left to right, and the bits within each byte are received right to left (LSB to MSB). The actual transmitted
and received bits are in the order of 10000000 11000100 10100010 11100110 10010001 11010101.
