Enable Jabber protection
Jabber is the condition in which a transmitter is stuck on
longer than 50 ms, preventing other stations from
transmitting.
Set this bit to 1 to enable Jabber protection logic within the
PE10T in ENDEC mode.
Bit mode
Set this bit to 1 to configure the MAC to operate in ENDEC
mode. ENDEC mode is based on the
bit-clock rather than the nibble-clock, and changes decodes
(such as Excess Defer) to operate accordingly.
