您好：
想請教一下， 使用TBLWTL及TBLWTH對Opcode做修改時， 是直接覆蓋還是做AND的動作？ 目前測試似乎是XOR的動作， 例： 1.原Opcode = 0xFF ，寫入0x09，結果0x09 2.原Opcode = 0xF6 ，寫入0x69，結果0x60 那如果我需要直接覆蓋的話， 該如何做修改呢？ 謝謝 PROG_ADDR = 013E6; TBLPAG = 0; test = 0xF6;//Address : 013E6, Opcode : B3CF60 code： SR_temp = SR; SR = 0x00E0; NVMCON = 0x4003; TBLPAG = (PROG_ADDR & 0x7F0000)>>16; addrOffset = PROG_ADDR & 0x00FFFF; asm("tblwth %1, [%0]" : "=r"(addrOffset) : "d"(0x00B3)); asm("tblwtl %1, [%0]" : "=r"(addrOffset) : "d"(0x0690)); NVMKEY=0x55; NVMKEY=0xAA; NVMCONbits.WR = 1; while(NVMCONbits.WR){} asm("NOP"); asm("NOP"); SR = SR_temp;
