This register provides control and reports the status of the RW8D.
FOCA
The force out-of-character-alignment bit (FOCA) controls the operation of the character
alignment block. A transition from logic zero to logic one in this bit forces the character
alignment block to the out-of-character-alignment state where it will search for the transport
frame alignment character (K28.5). This bit must be manually set to logic zero before it can
be used again.
FOFA
The force out-of-frame-alignment bit (FOFA) controls the operation of the frame alignment
block. A transition from logic zero to logic one in this bit forces the frame alignment block to
the out-of-frame-alignment state where it will search for the transport frame alignment
character (K28.5). This bit must be manually set to logic zero before it can be used again.
OCAV
The out-of-character-alignment status bit (OCAV) reports the state of the character alignment
block. OCAV is set high when the character alignment block is in the out-of-character-
alignment state. OCAV is set low when the character alignment block is in the in-character-
alignment state.
