Status bit
Clear the AMODE status bit in Status Register ST1, enabling C27x/C28x
addressing (see Chapter 5).
Note: This instruction does not flush the pipeline.
This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
#VarA
OPCODE
; Full C2xLP address-compatible mode
; Tell assembler we are in C2xLP mode
; Initialize DP (low 64K only)
; ACC = VarA (ACC high = 0)
; ACC = ACC + VarB (unsigned)
; Store result into VarC
; Return to C28x address mode
; Tell assembler we are in C28x mode
