幫助理解記憶指針
PC = progammer counter //程序計數器ci
ACC = accumulate //累加器it
PSW = progammer status word //程序狀態字io
SP = stack point //堆棧指針ast
DPTR = data point register //數據指針 寄存器定時器
IP = interrupt priority //中斷優先級請求
IE = interrupt enable // 中斷使能程序
TMOD = timer mode //定時器 方式 (定時器/計數器 控制寄存器)im
ALE = alter (變動,多是)數據
PSEN = progammer saving enable //程序存儲器使能(選擇外部程序存儲器的意思)
EA = enable all(容許全部中斷)完整應該是 enable all interrupt
PROG = progamme (程序)
SFR = special funtion register //特殊功能寄存器
TCON = timer control //定時器控制
PCON = power control //電源控制
MSB = most significant bit//最高有效位
LSB = last significant bit//最低有效位
CY = carry //進位(標誌)
AC = assistant carry //輔助進位
OV = overflow //溢出
ORG = originally //起始來源
DB = define byte //字節定義
EQU = equal //等於
DW = define word //字定義
E = enable //使能
OE = output enable //輸出使能
RD = read //讀
WR = write //寫
中斷部分:
INT0 = interrupt 0 //中斷0
INT1 = interrupt 1//中斷1
T0 = timer 0 //定時器0
T1 = timer 1 //定時器1
TF1 = timer1 flag //定時器1 標誌 (實際上是定時器1中斷標誌位)
IE1 = interrupt exterior 【ik'stiəriə】外部的//(外部中斷請求,多是)
IT1 = interrupt touch //(外部中斷觸發方式,多是)
ES = enable serial //串行使能
ET = enable timer //定時器使能
EX = enable exterior //外部使能(中斷)
PX = priority exterior //外部中斷優先級
PT = priority timer //定時器優先級
PS = priority serial //串口優先級
