New Instruction: MOVX @DPTR1,A
Instruction Code: 0xA5
Instruction Cycle: 1
Instruction Operation:
step-1. write ACC @DPTR1 into xdata SRAM embedded chip
step-2. increase DPTR1
ASM example:
INC XBUS_AUX
MOV DPTR,#TARGET_ADDR ;DPTR1
DEC XBUS_AUX
MOV DPTR,#SOURCE_ADDR ;DPTR0
MOV R7,#xxH
LOOP: MOVX A,@DPTR ;DPTR0
INC DPTR ;DPTR0, if need
.DB 0xA5 ;MOVX @DPTR1,A & INC DPTR1
