18.3. Remote Terminal 1 (RT1) Current Command Register (0x0002)
These 16-bit registers are read-only and are fully maintained by the device. These registers are cleared after MR pin
master reset, but are unaffected by assertion of RTxRESET remote terminal software reset in the Master Status and
Reset Register (0x0001).
This register contains the last valid command word received by the Remote Terminal over either MIL-STD-1553 bus.
This register is updated 5µs after the ACTIVE output is asserted.

HOLT INTEGRATED CIRCUITS
Function
Remote Terminal Address Lock.
This bit reflects the state of the LOCK input pin that applied at the rising
edge of the MR master reset input signal. After reset, the host can
overwrite bits 15-9 only if register LOCK bit 9 is logic 0. When the LOCK
bit is high, the host cannot overwrite register bits 15-9. To restore host
write capability for these bits, the MR master reset input signal must first
be asserted with the LOCK input pin held low to restore register LOCK
bit 9 to logic 0.
These bits are not used.
No Data Mode Command Flag.
Receive Data Mode Command Flag.
Transmit Data Mode Command Flag.
These three bits reflect the type of command stored in the RT Current
Command Register:
Subaddress, not mode code
Remote Terminal Address Parity Fail.
This bit is set when RT address parity error occurs for the value
contained in register bits 15-10. It is low when correct odd parity applies
for bits 15-10.
These bits are not used.
