Bits 7-0: EXP_C2 [7:0]

The received C2 bytes are monitored so that reception of the correct type of payload can be verified. When

aconsistent C2 value is received for five consecutive frames, it is written to RX_C2 [7:0], and the RX_C2_D delta bit is set. The expected value of the received C2 bytes is provided in EXP_C2 [7:0]. Its value after reset is 0x18 which indicates the mapping of a LAPS framed signal. If the received value does not match the expected value, and it is NOT:

all zeros unequipped label

0x01 equipped, non-specific label

0xFC payload defect label

0xFF reserved label

then the Payload Label Mismatch register bit, RX_PLM, is set to one.

If the current accepted value is the all zeros unequipped label, and EXP_C2[7:0] 0, then the unequipped register bit, RX_UNEQ, is set to one.
