今天读公司的旧代码，看到了老的PIC单片机配置配置字的方法，就把网上质料稍稍整理了一下。
平台为：MPLAB V8.92，这个ID有两个编译选项：DEBUG和RELEASE，那么可以根据系统预定宏来自动根据选择模式，配置配置字。
一、PIC18F系列配置字编写
MUC: PIC18F4550
IDE: MPLAB V8.92
编译器：MCC18 V3.47
配置字讲解帮助手册在编译器如下目录：doc\hlpPIC18ConfigSet.chm
例如：D:\Program Files\Microchip\mplabc18\v3.47\doc\hlpPIC18ConfigSet.chm
注意：配置字文件必须只能有main.c文件包含。。。。。。
配置字编写：以18F为例
#ifdef __DEBUG
#pragma config EBTRB = OFF
#else
#pragma config EBTRB = ON
#endif
这段代码就编译预定义宏__DEBUG，然后根据用户选择编译模式自动打开和关闭读保护
例子：
#ifdef __18F46K80
#ifdef I_WANNA_DEBUG
#pragma config XINST=OFF,SOSCSEL=DIG,RETEN=ON,INTOSCSEL=LOW,\
PLLCFG=ON,FOSC=HS2,\
