4-16 Using the LSI Logic Assembler NASM™
4.9.3 TARGET
By setting or clearing this bit, the SCRIPTS processor is placed in the
target or the initiator role. This must be done before the chip can execute
target or initiator specific operations, such as reselection. Usage:
SET TARGET
4.9.4 CARRY
This keyword checks the ALU Carry bit in the SCRIPTS processor to
determine which SCRIPTS routine to execute next. CARRY is not valid
if phase or data clauses are used in the same instruction. Register Move
(arithmetic) operations also affect the CARRY flag. Usage:
JUMP address, IF CARRY
4.10 Qualifier Keywords
Qualifier keywords are used in conjunction with action keywords to add
details about the instructions to be performed.
4.10.1 DSAREL
This keyword is only available in the LSI Logic devices that support Load
and Store instructions. It is used in Load/Store instructions to indicate
that the data to be loaded or stored is relative to the DSA register. This
keyword replaces the RELATIVE keyword, although NASM still supports
RELATIVE as well. Usage:
STORE NOFLUSH SCRATCHA0, 4 DSAREL (address)
4.10.2 FROM
This signifies use of table indirect addressing. It can be used with Block
Move or Select operations. Usage:
MOVE FROM address, WITH phase
4.10.3 MASK
This keyword allows selective comparison of specified bits with the SFBR
register. Any bits that are set in the mask byte eliminate the
