Bits 7-4: K2_CONSEC_NUM[3:0]: This 4 bit register is used to keep track of the number of consecutive
occurrences of LAIS and LRDI in order for the presence/absence of LAIS or LRDI to be detected
and the monitors to be updated accordingly.
Bit 3: RX_LOS_LEVEL is set to indicate RX_LOS is active low.
Bit 2: RX_LOS_INH is set to inhibit the contribution of RX_LOS to LRDI.
Bit 1: RX_FRAM_INH: If 1, the HDMP-3001 receive framer is enable and the parallel input signal is not
assumed to be byte aligned. If 0, the receive framer in the HDMP-3001 is bypassed, and it requires
a frame start condition, RX_FRAME_IN, as well as data and clock.
Bit 0: RX_LOF_ALG: If 1, RX_LOF will be cleared after RX_OOF is inactive for 8 consecutive frames.
If 0, RX_LOF will be cleared after RX_OOF is inactive for 24 consecutive frames.

ADDR=0x101: Receive Framer Position Control
Bits 7-4: Reserved
Bits 3-0: RX_FRAME_POSITION [3:0] – These four bits control the relationship between the data
bytes on the input bus RX_DATA [7:0] and the RX_FRAME_IN clock pulse. Please refer to
Table 21.
