我是用 PIC18, 使用 C18 compiler
TBLPTR = Offset; FSR0 = (unsigned short) &Buf[0]; for(i = 0; i < 64; i++) { TABLAT = Buf[i]; _asm TBLWT _endasm EECON1bits.WREN = 1; INTCONbits.GIE = 0; EECON2 = 0x55; EECON2 = 0xAA; EECON1bits.WR = 1; EECON1bits.WREN=0; INTCONbits.GIE=1; TBLPTR++; } 以上是我寫 64 bytes 的資料， 但是寫到 flash 後，後面總是有好幾個 bytes 資料會錯掉， 不知是我程式哪有問題？ 另外，有寫 flash 的 sample code 可以參考一下嗎？
