I'm trying to move data to external ram ADDR. 0x0000, increment the address and move the data to that address and so on. I never get my data at ADDR.0x0000. Can someone help me with this code?




ORG 0

SETUP:

MOV DPTR,#0000h
CLR A
MOV TCON,#0C0h ; Load 1100 0000
MOV TMOD,#21h ; Load 0010 0001
MOV S0CON,#57h ; Load 0101 0111
MOV TH1,#0FDh ; 19,200 baud
SETB EA
CLR ET0

START:

MOV A,S0BUF ;Move data to A
MOVX @DPTR,A ; move A to address 0x0000
INC DPTR
CLR A
CJNE A,#0Ah,START
END
