4. Stores the Command Word received.
5. Reads a Block address from the Look-Up Table
using the T/R bit and the subaddress from the
Command Word; transfers the Block address into
the address register. Data words are transferred
to/from memory by the associated 1553 interface
unit using the address register.

At the end of a 1553 message (valid or invalid) the
CT2566 received an EOM pulse and then performs the
following:
1. Updates the Block Status Word.
2. Updates the Time Stage if used.
3. Increments the Stack Pointer by four.
4. Generates an Error Interrupt if enabled.
