BCRTM

Aeroflex UTMC 

The descriptors, numbered sequentially from 0 to 15,

correspond to mode codes 0 to 15 without data words and

mode codes 16 to 31 with data words. For example, mode

codes 0 and 16 correspond to descriptor 0 and mode codes

1 and 17 correspond to descriptor 1. The Mode Code

Descriptor Space is appended to the Subaddress Descriptor

Space starting at 0100H (256D) of the 320-word RT

Descriptor Space (see figure 5).

The BCRTM can autonomously support all mode codes

without data words by executing the specific function and

transmitting the 1553 status word. The subsystem provides

the data word for mode codes with data words (see the Data

List Pointer section). For all mode codes, an interrupt can

be asserted by setting the appropriate bit in the control word

upon successful completion of the mode command by

setting the appropriate bit in the control word (see figure 9b).

Dynamic Bus Control #00000

This mode code is accepted automatically if the Dynamic

Bus Control Enable bit in the Remote Terminal Address

Register is set. Setting the Dynamic Bus Control

Acceptance bit in the 1553 status word and BCRTM Status

Register confirms the mode code acceptance. A High-

Priority Interrupt is also asserted if enabled. If the Dynamic

Bus Control Enable bit is not set, the BCRTM does not

accept Dynamic Bus Control.

Synchronize (Without Data Word) #00001

If enabled in the Mode Code #00001 Descriptor Control

Word, the BCRTM asserts an interrupt when this mode code

is received.

Transmit Status Word #00010

The BCRTM automatically transmits the 1553 status word

corresponding to the last message transacted.

Initiate Self-Test #00011

The BCRTM automatically starts its BIT routine. An

interrupt, if enabled, is asserted when the test is completed.

The BIT Word Register and external pin BCRTF are updated

when the test is completed. A failure in BIT will also set the

TF status word bit.

Transmitter Shutdown #00100

The BCRTM disables the channel opposite the channel on

which the command was received.

Override Transmitter Shutdown #00101

The BCRTM enables the channel previously disabled.

Inhibit Terminal Flag Bit #00110

The BCRTM inhibits the Terminal Flag from being set in

the status word.

Override Inhibit Terminal Flag Bit #00111

The BCRTM disables the Terminal Flag inhibit.

Reset Remote Terminal #01000

The BCRTM automatically resets the encoder, decoders,

and protocol logic.

Transmit Vector Word #10000

The BCRTM transmits the vector word from the location

addressed by the Data List Pointer in the Mode Code

Descriptor Block.

Synchronize (with Data Word) #10001

On receiving this mode code, the BCRTM simply stores the

associated data word.

Transmit Last Command #10010

The BCRTM transmits the last command executed and the

corresponding 1553 status word.

Transmit BIT Word #10011

The BCRTM transmits BIT information from the BIT

Register.

Selected Transmitter Shutdown #10100

On receiving this mode code, the BCRTM simply stores the

associated data word.

Override Selected Transmitter Shutdown #10101

On receiving this mode code, the BCRTM simply stores the

associated data word.
