Example
; Execute the operation "VarC = VarA + VarB" written in
; C2xLP syntax:
LPADDR
.lp_amode
LDP
LACL VarA
ADDS VarB

Clear the AMODE status bit in Status Register ST1, putting the device in
C27x/C28x addressing mode (see Chapter 5).
Note: This instruction does not flush the pipeline.
The AMODE bit is cleared.
This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
#VarA
Clear the AMODE Status Bit
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
