Standard Interrupt Pulse. STDINTP pulses when an inter-

rupt is logged.

High Priority Interrupt. The High-Priority Interrupt level

is asserted upon occurrence of events enabled in the High

Priority Interrupt Enable Register. The corresponding

bit(s) in the High-Priority Interrupt Status/Reset Register

reset HPINT.

(RT)Timer On. This is a 760-microsecond fail-safe trans-

AL

mitter enable timer. Started at the beginning of a transmis-

sion. TIMERON goes inactive 760 microseconds later or

is reset automatically with the receipt of a new command.

Use it in conjunction with CHA/B output to provide a fail

safe timer for channel A and B transmitters.

(RT) Command Strobe. The BCRTM asserts this

AL

signal after receiving a valid command. The BCRTM deac-

tivates it after servicing the command.

Subsystem Fail. Upon receipt, this signal propagates

AH

directly to the RT 1553 status word and the BCRTM

Status Register.
