MAC Additional Station Address Low Register (MAAL0-15)
The KSZ8841-PMQLsupports 16 additional MAC addresses for MAC address filtering. This MAC address is used to
define one of the 16 destination addresses that the KSZ8841-PMQL 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.
