GENERAL
The CT2553 is a complete MIL-STD-1553 bus
interface
unit
containing
transceivers; Bus Controller (BC), Remote
Terminal (RTU), and Bus Monitor (MT) protocol
logic; 8K x 16-bit pseudo dual port RAM; and
memory management arbitration control circuitry.
The host processor interface consists of standard
control and interrupt signals, memory expansion
capability and non-multiplexed address and data
buses.
Control of the CT2553 is accomplished entirely
through the use of three internal registers and the
dual
low-power
shared RAM. Transfers to and from the CT2553
are executed on a word-by-word basis ensuring
minimal wait time if contention occurs.
The
specific
mods
BC/RTU/MT) is software programmable. Memory
is configured into unique control and data block
areas based on the 1553 mode of operation.
External registers are also supported by the
CT2553 for manipulation of user data. In addition,
the CT2553 provides dynamic, online and
software initiated self-test capabilities.
