Send Pad character
0 = CD2401 does not send any pad characters.
1 = CD2401 sends pad characters before sending SYN when coming out of the Idle-
In Mark mode.
Send pad pattern
0 = hex AA is sent as pad character.
1 = hex 55 is sent as pad character.
FCS Preset
0 = FCS is preset to all ‘0’s.
1 = FCS is preset to all ‘1’s.
FCS mode
0 = normal FCS mode. The CD2401 generates and appends CRC on transmit and
validates CRC on receiving, using the CRC polynomial selected through CPSR.
1 = disable FCS generation and checking. The CD2401 treats the entire frame as
data.
Idle mode
0 = idle in SYN.
1 = idle in mark.
Pad count [2:0] – transmit frame leading pads
These bits specify the number of pad characters to be sent when coming out of Idle-
In Mark mode.
