HOLT INTEGRATED CIRCUITS
Function
Good Data Block Transfer.
Indicating status for the last transmit-data message, this bit is set to
logic 1 after completion of an error-free RT-to-BC transfer, RT-to-RT
transfer, or transmit mode command with data. This bit is reset to logic
0 following any message in which error occurs. This bit is always logic
0 after completion of a BC-to-RT transfer, a receive mode command
with data, or any mode command without data. This bit can be used
to determine when the transmit portion of an RT-to-RT message was
error-free: A Block Status Word for an RT-to-RT message having both
the Error Flag and Good Data Block Transfer bits set indicates that
the transmitting RT responded correctly, but an error was detected in
the receiving RT portion of the message. This bit is not affected by the
device loop back function.
Format Error.
This bit is logic 1 when the received data from the most recent message
contains one or more violations of the MIL-STD-1553 message
validation criteria, including sync, encoding, parity, bit count or word
count errors.
This bit is also set if the received Status Word from the responding RT
contains incorrect RT address bits 15:10.
No Response Error.
This bit is set to logic 1 when an RT fails to respond to a command,
or responds later then the BC No Response Timeout time. The No
Response Timeout delay is programmed using BC Timeout Select bits
15-14 in the BC Configuration Register 0x0032.
General Purpose Flags 7-2.
Interpretation of these flag bits is user defined. These bits are set
cleared or toggled by the host, through use of the BC General Purpose
Flag Register, or by the BC, through use of the FLG instruction op code.
Equal / General Purpose Flag 1.
This flag bit is manipulated using the same methods as General
Purpose Flags 7-2, or may be set or cleared by two BC instruction op
codes, Compare to Frame Time Counter (CFT) or Compare to Message
Time Counter (CMT).
Less Than / General Purpose Flag 0
This flag bit is manipulated using the same methods as General
Purpose Flags 7-2, or may be set or cleared by two BC instruction
op codes, Compare to Frame Time Counter (CFT) or Compared to
Message Time Counter (CMT).
