• Description: Mil-std-1553 / Mil-std-1760 3.3v Bc / Mt / Rt Multi-terminal Device
• Manufacturer: QuickLogic Corp

18.6. Remote Terminal 1 (RT1) MIL-STD-1553 Status Word Bits Register (0x001A)
These 16-bit registers are Read-Write. With the exception of bits 4 and 10, these registers are maintained by the host.
These registers are cleared after MR pin master reset, or by assertion of RTxRESET remote terminal software reset
in the Master Status and Reset Register (0x0001).
Register bits 14-10 and 7-4 are read-only. Most of these bits read back zero, except for bits 4 and 10, which are main-
tained by the device. The remaining bits in the register are Read-Write and are maintained by the host. All bits are
active high. Register bits 10-0 are reflected in the outgoing MIL-STD-1553 RT status word. The RT status word reflects
the state of host-written register bits until overwritten by the host, unless the Transmit and Clear function (bit 15) is
enabled. When set, the Transmit and Clear bit resets itself and bits 9-5 and 3-0 after the next transmitted status word.

HOLT INTEGRATED CIRCUITS

Function
Transmit and Clear.
When this bit is set, it resets itself and bits 9-5 and 3-0 after the next
transmitted status word. This bit does not affect operation of the
Transmit Status Word and Transmit Last Command mode codes.
Example: Transaction of a valid legal command with the INST and
TXANDCLR bits asserted results in status word transmission with the
Instrumentation bit set. If the following command is Transmit Status or
Transmit Last Command mode code, the Instrumentation bit remains
set.
These bits are not used, cannot be written, always read back 000.
Message Error status bit.
The device maintains this read-only bit, based on prior message results.
Instrumentation status bit.
The host maintains this read-write bit.
Service Request status bit.
The host maintains this read-write bit.
These bits are not used, cannot be written, always read back 000.
Broadcast Command Received status bit.
The device maintains this read-only bit, based on prior message results.
