TFE
Bits: 11
RT
1= Indicates that the TERMINAL FLAG bit in the status word can be set to a "1" . This can be
done in the BASIC STATUS REGISTER or by the TERMINAL FLAG pin on the NHi-ET. This
bit is set to a "1" at POWER UP, if the NHi- ET is RESET, after receipt of a RESET MODE
CODE, or after receipt of an OVERRIDE INHIBIT TERMINAL FLAG mode code.
0= Indicates that the TERMINAL FLAG bit in the status word CANNOT be set to a "1". This bit is
set to a "0" after receipt of an INHIBIT TERMINAL FLAG mode code.
MDCD_ L
Bits: 9
RT
1= Indicates that the last command received was NOT a mode code.
0= This bit is set to a "0" when a mode code is received.
CUFRM BUSY
Bits: 6
BC/ MT
1= The current frame of data block is busy.
It is active and could be receiving or transmitting
data.
EOF B
Bits: 5
BC/ MT
1= Frame "B" or data block "B" has finished processing data and in now inactive.
EOF A
Bits: 4
BC/ MT
1= Frame "A" or data block "A" has finished processing data and in now inactive.
CUR FRM
Bits: 3
BC/ MT
0= Frame "A" or block "A" is the current active frame of block.
1= Frame "B" or block "B" is the current active frame of block.
CUR_ BUS
Bits: 2
BC/ MT
0= Bus "A" is the current bus.
1= Bus "B". is the current bus.
BUSJAM B
Bits: 1
BC
1 = Bus "B" has been jammed by continuous transmission from an RT. This condition is
indicated when an RT transmits more extra words then the value set in CONFIGURATION
REGISTER 3 (See CONFIG REG 3 for details).
BUSJAM A
Bits: 0
BC
1 = Bus "A" has been jammed by continuous transmission from an RT. This condition is
indicated when an RT transmits more extra words then the value set in CONFIGURATION
REGISTER 3 (See CONFIG REG 3 for details).
4.2.18
ENCODER DATA REGISTER
Address: 23
R/W
RT
This register contains data to be transmitted when performing a loop back test.
4.2.19
ENCODER DATA TRANSMIT RQST
Address: 24
W
RT
Writing (any value) to this address causes the contents of the ENCODER DATA REGISTER to be
sent as a data word. This instruction together with the ENCODER COMMAND TRANSMIT
REQUEST can be used to loop- back entire messages for self- test purposes. The received data
can be read from the data table associated with the command.
4.2.20
ENCODER COMMAND TRANSMIT REQUEST
Address: 25
W
RT
Writing (any value) to this address causes the contents of the ENCODER DATA REGISTER to be
sent as a command word. This instruction is useful for sending commands to the decoder while
in loop- back mode. The command can then be read from the LAST COMMAND register.
