Type
10-bit These define minus-comma for the purpose of raising
vector RXCOMMADET and realigning the serial bit stream byte boundary.
This definition does not affect 8B/10B encoding or decoding. Also
see COMMA_10B_MASK.
Boolean TRUE/FALSE indicates whether to raise or not raise the
RXCOMMADET when minus-comma is detected.

Boolean TRUE/FALSE indicates whether to raise or not raise the
RXCOMMADET when plus-comma is detected.
Integer This masks the startup sequence of the PMA and must always be set
to all ones.
(
String 13_40) Selects the mode of the PMA. Refer to PMA section for the
proper mode selection.
Boolean TRUE/FALSE. Recommended to always be set to TRUE. Enables the
use of the receive side buffer. When set to TRUE, the buffer is enabled.
Integer Power of two in a range of 1 to 128 that denotes the number of valid
characters required to "cancel out" appearance of one invalid
character for loss of sync determination.
Integer Power of two in a range of 4 to 512. When divided by
RX_LOS_INVALID_INCR, denotes the number of invalid
characters required to cause FSM transition to "sync lost" state.
Boolean Undefined.
8-bit 8-bit binary; controls when the 64B/66B synchronization state
vector machine enters synchronization. (max sync header count)
8-bit 8-bit binary; controls when the 64B/66B synchronization state
vector machine leaves synchronization. (max invalid sync header count)
Boolean When set to TRUE, this enables the use of the transmit buffer.
