The E_CAL_M value programmed defines the number of times the calendar
sequence is repeated before a DIP-2 parity and “1 1” framing words are inserted
The actual CALENDAR_M value used is one more than the value programmed into
the E_CAL_M field.
This field specifies the egress calendar 0 length.
In LVTTL mode, the E_CAL_LEN can be programmed with any value.
In LVDS mode, it should be programmed with 4n-1, where n is an integer.Indicates
the length of the egress calendar 0
is E_CAL_LEN+1.
