我在学AVR单片机，仿真软件是IAR Embedded Workbench IDE.
我编了一个汇编程序，编译有错误
程序如下：
.device AT90S8535
.equ PORTB =$18
.equ DDRB =$17
.equ PINB =$16
.equ SPH =$3E
.equ SPL =$3D
.equ EECR =$1C
.equ EEDR =$1D
.equ EEARH =$1F
.equ EEARL =$1E
.def ZH =r31
.def ZL =r30
rjmp RESET

sbic EECR,01
rjmp EEWrite
out EEARH,r18
out EEARL,r17
out EEDR,r16

我估计是没添加头文件造成的。
可是我不知道该加哪个，请高手指教，谢谢！
