MT DATA STORAGE.
Figure 26 shows the steps
in a MT data Storage operation.
INTERRUPTS
: SA/MC - 0 (pin 13), SA/MC - 1
(pin 52) and SA/MC - 2 (on 52) represents B6,
B7, and B8 counter outputs in the MT mode. B6
counts every 32 words transferred, B7 every 64
words, and B8 every 128 words. These counter
outputs can be used to generate interrupts to the
subsystem to insure proper servicing of Memory.
The Data Word and Identification Word transfers
increment the counter by two.
BUILT-IN-TEST WORD (RTU MODE)
The CT2553 contains a 14 bit Built-In-Test (BIT)
word register which stores information about the
condition of the RTU. When a Mode Command is
received to transmit BIT word, the contents of this
register are transmitted over the 1553 data bus.
Figure 27 shows the meaning of each bit in the
BIT register. Information is included regarding
transmitter timeouts, loop test failures, transmitter
shutdown, subsystem handshake failure, and the
results of individual message validations.
MODE CODES
The CT2553 implements all mode codes
applicable to dual redundant systems. Mode
codes can also be illegalized using the
appropriate
I/O
signals.
illegalization and handling are detailed in the RTU
Operation section and listed in Table 6.

Notes:
(1) Bits 0-2 and 10-13 are latched and only cleared by a mode reset command or a master RESET.
(2) Bits 3-7 are cleared at the start of each new message and updated at the end of the message. They
reflect the present command word.
(3) Bits 8-9 are set by the mode command for Transmitter Shutdown and are cleared by the mode
command for Override Transmitter Shutdown, Reset RT or a master RESET.
