3-46 The SCSI SCRIPTS Processor Instruction Set
If the command code is vendor unique, the SCRIPTS processor uses the
byte count from the instruction. If this byte count is zero, the chip issues
an illegal instruction interrupt.
For LSI53C825A, LSI53C875, LSI53C876, LSI53C885, LSI53C895,
LSI53C895A, LSI53C896, LSI53C1000, LSI53C1010, LSI53C1010R,
LSI53C1000R only: If the SCSI group code is either Group 0, 1, 2, or 5
and if the Vendor Unique Enhancement bit 1 (VUE1) bit (SCNTL2 bit, 1)
is cleared, the SCRIPTS processor overwrites the DBC register with the
length of the CDB: 6, 10, or 12 bytes. If the Vendor Unique Enhancement
1 (VUE1) bit (SCNTL2, bit 1) is cleared and the SCSI group code is a
vendor unique code, the chip receives the number of bytes in the count.
If the VUE1 bit is set, the chip receives the number of bytes in the byte
count regardless of the group code.

3.2.12 MOVE MEMORY
MOVE MEMORY[NO FLUSH]count, source_address,
destination_address
Supported by All LSI Logic SCSI SCRIPTS Processors; No Flush option is available on
all SCRIPTS processors except for the LSI53C770.
Definition Memory-to-Memory Move (DMA).
Operands This command has the following operands:
NOFLUSH Allows the SCRIPTS processor to perform the Move
Memory without flushing the prefetch buffer.
count A 24-bit expression which indicates the number of bytes
to transfer.
source_address Absolute 32-bit starting address of the data in memory.
destination_address Absolute 32-bit destination address of where to move the
data.
