This register allows control over the path signal label. Upon reset the register
defaults to 0x01, which signifies an equipped unspecific payload.
C2[7:0]:
The C2[7:0] bits are inserted in the C2 byte position in the transmit stream.
C2 should be reprogrammed with the value 0x13 when transmitting ATM
payload data.
C2 should be reprogrammed with the value 0x16 when transmitting
scrambled packet over SONET payload data.
C2 may be reprogrammed with the value 0xCF when transmitting
unscrambled packet over SONET payload data. However, POS scrambling in
the TXFP block must be turned off.
