PC = progammer counter //程序计数器

ACC = accumulate //累加器

PSW = progammer status word //程序状态字

SP = stack point //堆栈指针

DPTR = data point register //数据指针 寄存器

IP = interrupt priority //中断优先级

IE = interrupt enable // 中断使能

TMOD = timer mode //定时器 方式 (定时器/计数器 控制寄存器)

ALE = alter (变更,可能是)

PSEN = progammer saving enable //程序存储器使能(选择外部程序存储器的意思)

EA = enable all(允许所有中断)完整应该是 enable all interrupt

PROG = progamme (程序)

SFR = special funtion register //特殊功能寄存器

TCON = timer control //定时器控制

PCON = power control //电源控制

MSB = most significant bit//最高有效位

LSB = last significant bit//最低有效位

CY = carry //进位(标志)

AC = assistant carry //辅助进位

OV = overflow //溢出

ORG = originally //起始来源

DB = define byte //字节定义

EQU = equal //等于

DW = define word //字定义

E = enable //使能

OE = output enable //输出使能

RD = read //读

WR = write //写

中断部分:

INT0 = interrupt 0 //中断0

INT1 = interrupt 1//中断1

T0 = timer 0 //定时器0

T1 = timer 1 //定时器1

TF1 = timer1 flag //定时器1 标志 (其实是定时器1中断标志位)

IE1 = interrupt exterior 【ik'sti?ri?】外部的//(外部中断请求,可能是)

IT1 = interrupt touch //(外部中断触发方式,可能是)

ES = enable serial //串行使能

ET = enable timer //定时器使能

EX = enable exterior //外部使能(中断)

PX = priority exterior //外部中断优先级

PT = priority timer //定时器优先级

PS = priority serial //串口优先级
