3 4 5 7 Flow Control Instructions
NOPR No Operation
The NOPR command passes control to the next command
in the command list No operation is performed
Syntax
NOPR
Note Accumulator is not affected
HALT Terminate Command-List Execution
The HALT command terminates execution of the command
list No further commands are executed This event is made
visible to the CPU core as specified in Section 3 6
Syntax
HALT
Note Accumulator is not affected
DJNZ Decrement and Jump If Not Zero
The DJNZ command is used to implement loops and
branches in the command list The value of the REPE-
AT COUNT field is decremented by 1 and compared to 0 If
it is not equal to 0 then execution of the command list con-
tinues with the command located in the RAM address speci-
fied
REPEAT COUNT field is equal to 0 then execution contin-
ues with the next command in the command list
The DSPM has only one REPEAT register To nest loops
user must save the contents of the REPEAT register before
starting an inner loop and restore it at the end of the inner
loop
