17. SINGLE OR DUAL REMOTE TERMINAL(S) − OVERVIEW
The HI-613x can operate as one or two autonomous MIL-STD-1553 Remote Terminals, requiring minimal host support.
When a single Remote Terminal (RT) is enabled, its configuration and operation is nearly identical to the Holt HI-612x
integrated circuit. When two RTs are enabled, they operate simultaneously and independently, with the full flexibility
of the Holt HI-612x remote terminal architecture. Designated as RT1 and RT2, the configuration registers for the two
terminals are completely duplicated, although certain (i.e., interrupt management) registers are shared between the
two RTs. Each terminal has its own Descriptor Table, command Illegalization Table and host interrupt configuration.
The discrete input / output pins for the two Remote Terminals are completely duplicated. The following signal pins are
provided for Remote Terminals RT1 and RT2:
By writing the Master Status and Reset Register, Remote Terminals RT1 and RT2 can be independently reset using
“soft reset”. Either or both RTs can be configured to automatically assert soft reset when a valid “Reset Remote
Terminal” mode code command is received. In this configuration, the serial auto-initialization EEPROM should already
be programmed with the desired attributes for the two terminals. When a broadcast “Reset Remote Terminal” mode
command is received, RT1 and RT2 perform soft reset independently, although the read-from-EEPROM time interval
is doubled.
In this section of the data sheet, the Remote Terminal registers are described first, followed by the details for configuring
and operating one or both RTs.
