GO_ DEF_ FRAME
Bits: 15
BC/ MT
When a "1" is written to this bit,
the DEFAULT FRAME, defined by bit 12 in
CONFIGURATION REGISTER 1, is made the active frame.
ABORT
Bits: 14
BC/ MT
When a "1" is written to this bit,
all BC and MT processing is terminated and the NHi- ET goes
off- line. The BC or the MT must be re- started to again become active.
STOP END OF FRAME
Bits: 13
BC/ MT
When a "1" is written to this bit,
the BC or the MT will go off- line after the last message in the
frame or block has been processed. The BC or the MT must be re- started to again become
active.
STOP END OF MESSAGE
Bits: 12
BC/ MT
When a "1" is written to this bit, the BC or the MT will go off- line after the current message in
the frame or block has been processed. The BC or the MT must be re- started to again become
active.
CLR DISC FLAG
Bits: 11
RT
When a "1" is written to this bit, the 1760 DISCONNECT FLAG is cleared. This flag indicates
that a store has been released and all the address bits and the parity bit on the hardwire address
are "1's". The flag is read on the IPO_ DSC pin and bit 6 of the EXTERNAL TERMINAL
ADDRESS REGISTER.
GO EOF & CONTINUE
Bits: 10
BC
When a "1" is written to this bit after a BUS JAM condition has halted the BC operation, the BC
will ignore all further messages in the current frame, proceed to the end of the frame and perform
the programmed EOF operations.
GO NEXT MESSAGE
Bits: 9
BC
When a "1" is written to this bit after a BUS JAM condition has halted the BC operation, the BC
will abort the current message and NOT perform the programmed EOM operations; instead, the
next message in the frame will be activated. If there are no more messages in the frame, the
programmed EOF operations will be performed.
DO_ EOM & CONTINUE
Bits: 8
BC
When a "1" is written to this bit after a BUS JAM condition has halted the BC operation, the BC
will perform the programmed EOM operations, then the next message in the frame will be
activated. If there are no more messages in the frame, the programmed EOF operations will be
performed.
The contents of CONFIGURATION REGISTER 2 are not affected by these operations and all the
bits are always read by the host as "0" after the indicated action has been completed.
