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'stiəriə】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
