AR Area
These bits mainly serve as flags related to CQM1H operation. The flags in AR
05 and AR 06 relate to the operation of Inner Boards and their functions are
different for each Inner Board. The following table has been split to show the
functions of the shared flags (AR 00 to AR 04 and AR 07 to AR 27) and the
flags unique to particular Inner Boards (AR 05 and AR 06.)
With the exception of AR 23 (Power-off Counter), the status of AR words and
bits is refreshed each cycle. (AR 23 is refreshed only for power interruptions.)
