The SCSI SCRIPTS Processor Instruction Set

arbitration, the SCRIPTS processor continues to execute instructions
until an interrupt or any instruction related to the SCSI bus is issued. If
arbitration terminates because of a bus initiated selection or reselection,
the chip uses the 32-bit jump address value to fetch the next instruction
and begins execution at that address. When the instruction is completed
then the next sequential instruction is fetched and executed.

Notes

The REL keyword, which indicates relative addressing, is unrelated to the
declarative keyword RELATIVE that establishes relative buffers.

Legal Forms

SELECT scsi_id, address
SELECT FROM table_entry, address
SELECT ATN scsi_id, address
SELECT ATN FROM table_entry, address
SELECT scsi_id, REL(address)
SELECT FROM table_entry, REL(address)
SELECT ATN scsi_id, REL(address)
SELECT ATN FROM table_entry, REL(address)
