LBD
RBOC.7
Latched BOC Detected. A latched version of the BD status
bit (RBOC.6). Will be cleared when read.
BD
RBOC.6
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.
BOC5
RBOC.5
BOC Bit 5. Last bit received of the 6–bit code word.
BOC4
RBOC.4
BOC Bit 4.
BOC3
RBOC.3
BOC Bit 3.
BOC2
RBOC.2
BOC Bit 2.
BOC1
RBOC.1
BOC Bit 1.
BOC0
RBOC.0
BOC Bit 0. First bit received of the 6–bit code word.
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.
