LOPD[2:0] These bits can be changed condition of transition to LOP status.
000: Not detect 3×norm_point or 3×conc_ind of 1 or more H1#2 and H2#2 to H1#12
001: Not detect 3 consecutive norm_point and conc_ind of all H1#2 and H2#2 to
010: Not detect 3×norm_point in N frame (but not include AIS detection).
011: Detect N×Inv_point of H1#1 and H2#1 (but not include 3 x norm_point) or
100: Detect N×Inv_point of H1#1 and H2#1 (but not include 3 x norm_point).
Other than above: Reserved
D8-D7
LOPN[1:0] Sets the number of protection stages n for LOP detection in status transition of
pointer processing.
11: Reserved
D6 Reserved Set to 0.
D5-D4
SS[1:0] Sets the expected value of the SS bits to be verified if the SS bits are checked when
the receive pointer action is identified (when SSM = 1).
D3
SSM Selects whether the SS bits are checked when the receive pointer action is
identified.
D2 Reserved Set to 0.

FJM2 Select the incr_ind and decr_ind indication condition
1: Mach of 8 bits or more of the 10 bits I-bits and D-bits to either the increment and
decrement indication.
0: incr_ind : 3 or more I-bits are inverted and 3 or more D-bits are not inverted
decr_ind : 3 or more D-bits are inverted and 3 or more I-bits are not inverted
