AX51: ERRORS ASSEMBLING STARTUP.A51
Information in this article applies to:
When I use the AX51 assembler for my 8051 project, I receive the following error when I assemble the STARTUP.A51 file:
000006 141 MOV SP,#?STACK-1 *** ____________________________________________________^ *** ERROR #A45 IN 141 (STARTUP.A51, LINE 141): UNDEFINED SYMBOL
This error is caused by the SP sfr which is undefined. This SFR was defined automatically by the A51 assembler.
Define the SP SFR and the assembler will no longer generate this error. For example:
SP EQU 81h MOV SP,#?STACK-1
