C28ADDR Clear the AMODE Status Bit
SYNTAX OPTIONS OPCODE OBJMODE RPT CYC
C28ADDR 0101 0110 0001 0110 X − 1
Note: This instruction is an alias for the “CLRC AMODE” operation.

AMODE
The AMODE bit is cleared.
Repeat This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
Example
; Execute the operation ”VarC = VarA + VarB” written in
; C2xLP syntax:
LPADDR ; Full C2xLP address compatible mode
.lp_amode ; Tell assembler we are in C2xLP mode
LDP #VarA ; Initialize DP (low 64K only)
LACL VarA ; ACC = VarA (ACC high = 0)
ADDS VarB ; ACC = ACC + VarB (unsigned)
SACL VarC ; Store result into VarC
C28ADDR ; Return to C28x address mode
.c28_amode ; Tell assembler we are in C28x mode
