Chip Reset:
When the host changes the destination filter, it is possible that a frame will be missed while
SerRxON is clear.
Note: It may become necessary for the host to change the destination address filter criteria and

Individual Address Hash Accept. When set, received
frame are accepted when the DA is an Individual Address
(first bit of DA = 0), that is accepted by the hash table. See
Descriptor Processor Transmit Registers.
Individual Accept 3. When set, received frames are
accepted which the DA matches the Individual Address 3
Register.
Individual Accept 2. When set, received frames are
accepted which the DA matches the Individual Address 2
Register.
Individual Accept 1. When set, received frames are
accepted which the DA matches the Individual Address 1
Register.
Individual Accept 0. When set, received frames are
accepted which the DA matches the Individual Address 0
Register.
