本人刚刚学习用silicon laboratories IDE，有个问题想请教

程序如下：

;  TARGET MCU  :  C8051F060/1/2/3
; DESCRIPTION :  This program illustrates how to disable the watchdog timer,
;                 configure a port and write to a port I/O pin.

;-----------------------------------------------------------------------------

GREEN_LED      equ   P1.6              ; Port I/O pin connected to Green LED.

; RESET and INTERRUPT VECTORS

               ; Reset Vector
               cseg AT 0

请问，中间有些错误（比如“A51 FATAL ERROR”）是什么原因，如何改正？谢谢！

请教高手，问题出在哪？
