解释这段代码#ifndef __REG51_H__ #define __REG51_H__ /* BYTE Register */ sfr P0 = 0x80; sfr P1 = 0x90; sfr P2 = 0xA0; sfr P3 = 0xB0; sfr PSW = 0xD0; sfr ACC = 0xE0; sfr B = 0xF0; sfr SP = 0x81; sfr DPL = 0x82; sfr DPH = 0x83; sfr PCON = 0x87; sfr TCON = 0x88; sfr TMOD = 0x89; sfr TL0 = 0x8A; sfr TL1 = 0x8B; sfr TH0 = 0x8C; sfr TH1 = 0x8D; sfr IE = 0xA8; sfr IP = 0xB8; sfr SCON = 0x98; sfr SBUF = 0x99;

这段代码定义了一些特殊功能寄存器（SFR）的地址，这些寄存器是 8051 单片机的核心组成部分，可以用来控制输入输出、定时器、串行通信等硬件功能。这里的 sfr 关键字表示这些寄存器是特殊功能寄存器，而 P0、P1、P2、P3、PSW、ACC、B、SP、DPL、DPH、PCON、TCON、TMOD、TL0、TL1、TH0、TH1、IE、IP、SCON、SBUF 则是对应的寄存器地址。通过定义这些地址，可以方便地访问这些寄存器，从而控制相关硬件功能。
