Description
Defines whether reserved frames are accepted or not.
Reserved frames have frame type = (100, 101, 110, 111).
0 - Reject
1 - Accept
Defines whether MAC command frames are accepted or
not. MAC command frames have frame type = 011.
0 - Reject
1 - Accept
Defines whether acknowledgment frames are accepted or
not. Acknowledgement frames have frame type = 010.
0 - Reject
1 - Accept
Defines whether data frames are accepted or not. Data
frames have frame type = 001.
0 - Reject
1 - Accept.
Defines whether beacon frames are accepted or not.
Beacon frames have frame type = 000
0 - Reject
1 - Accept
These bits are used to modify the frame type field of a
received frame before frame type filtering is performed.
The modification does not influence the frame that is
written to the RX FIFO.
00 : Leave as it is
01 : Invert MSB
10 : Set MSB to ‘0’
11 : Set MSB to ‘1’
Reserved. Always write ‘0’
