3-40 The SCSI SCRIPTS Processor Instruction Set
Legal Forms LOAD register, byte_count, source_address
LOAD register, byte_count, DSAREL(source_address)
3.2.10 LOAD64
LOAD64 uses table indirect addressing only.
LOAD64 register, byte_count, [DSAREL(]source_address[)]
Supported by LSI53C896, LSI53C1000, LSI53C1010, LSI53C1010R, LSI53C1000R.
Definition Load 64-bit data from memory to an internal register of the chip.
Operands This command has the following operands:
Example LOAD64 SCRATCHA0, 4, data_buf
LOAD64 SCRATCHA3, 2, DSAREL (0x02)
Register Is one of the register names in the chip operating register set.
Byte Count Is the number of bytes [1:4] to be transferred from the
source_address.
DSA Relative Indicates that the source_address is an offset and should be
added to the DSA register to obtain the physical address
(DSA relative).
Source Address Is the physical address or offset from the DSA to obtain the
physical address of the data to be loaded into the register.
