RBOC: RECEIVE BIT ORIENTED CODE REGISTER (Address=04 Hex)
NOTE:
1. The LBD bit is latched and will be cleared when read.
2. The RBOC0 to RBOC5 bits display the last valid BOC code verified; these bits will be set to all ones on reset.

NAME AND DESCRIPTION
Latched BOC Detected. A latched version of the BD status bit (RBOC.6). Will be
cleared when read.
BOC Detected. A real–time bit that is set high when the BOC detector is presently
seeing a valid sequence and set low when no BOC is currently being detected.
BOC Bit 5. Last bit received of the 6–bit codeword.
BOC Bit 4.
BOC Bit 3.
BOC Bit 2.
BOC Bit 1.
BOC Bit 0. First bit received of the 6–bit codeword.
