从控制器保护代码

我的朋友，我使用PIC16F87A控制器在我的项目中。我喜欢从别人的复制程序中保证程序。//COFIG，Primamatlab配置，FoSC＝hs//振荡器选择位（HS振荡器）。能比特（PWRT-启用）的α-PrAPMA配置BRONE= OF//Brown OUT RESET允许位（BOR禁用）α-PrAPMA配置LVP= OF//Low Voltage（单电源）在电路串行编程使能位（RB3是数字I/O，MCU上的HV必须用于编程）α-PrAPMA CONFIG-CPD= ON//数据EEPROM存储器CODE保护位（数据EEPROM代码保护）α-PrimaMac配置WRT＝256／/Flash程序存储器写使能位（0 0 0～0 0 FFH写保护；0100H至1FFFH可由ECOCON控制）这是我的配置位，我启用了保护位，但是它们有没有提高安全性的方法来避免误用我的代码？

    Hai Friends,
I'm using PIC16F877A controller in my project.
I like to secure program from copying by others.

// CONFIG
#pragma config FOSC = HS        // Oscillator Selection bits (HS oscillator)
#pragma config WDTE = OFF       // Watchdog Timer Enable bit (WDT disabled)
#pragma config PWRTE = ON       // Power-up Timer Enable bit (PWRT enabled)
#pragma config BOREN = OFF      // Brown-out Reset Enable bit (BOR disabled)
#pragma config LVP = OFF        // Low-Voltage (Single-Supply) In-Circuit Serial Programming Enable bit (RB3 is digital I/O, HV on MCLR must be used for programming)
#pragma config CPD = ON         // Data EEPROM Memory Code Protection bit (Data EEPROM code-protected)
#pragma config WRT = 256        // Flash Program Memory Write Enable bits (0000h to 00FFh write-protected; 0100h to 1FFFh may be written to by EECON control)
#pragma config CP = ON          // Flash Program Memory Code Protection bit (All program memory code-protected)



This is my config bit I enabled the protection bits.But is their any way to improve the security to avoid the misuse of my code..?
