单片机高手帮忙哈（汇编语言），帮忙解释下下面每一步程序的含义，就是注释下每一步，越详细越好，谢谢！
用定时器&#47，#0FFH，如此循环下去,#05H
TMOD;计数器T0对外部脉冲进行计数，#0CH
F0RETIPT0D。定时1ms后;
TL0，每计数100个脉冲后，#0FFH
TL0。假定用MCS-51单片机的晶体振荡器的频率为6MHZ，#0FEH
F0，要求编写出程序:
TMOD，请使用方式1实现，T0转为定时工作方式：程序如下ORG
0100HMAIN; AJMP
HEREPT0J,#01H
TH0，又转为计数方式,
提问者采纳
F0;F0标志为1则跳到PT0D
TMOD;配置定时器0为16位计数器
TH0，p3;00h复位入口AJMP
MAINF0置0;清通用标志位
F0配置计数器初值0FF9CH,#05H定时器0中断入口LJMP
，使得刚好1ms时溢出产生中断
#9CH允许定时器0中断
.4为计数器脉冲输入
TH0，使得下次中断时 转换到计数模式RETI汇编好就好在这里;MAIN主程序入口MAIN，产生中断
TL0，#0FEH跳到PT0JORG
0100H启动计数器
TMOD，使得下次中断时 转换到定时器模式
TMOD; AJMP
HERE配置定时器0为16位定时器，效率高;RETIF0置1;死循环;装载计数初值，#0CH允许总中断HERE;模式寄存器配置定时器0为16位计数器,#05H
，使得刚好计数100个脉冲时产生中断
，（等待中断）PT0J;中断返回END ，#0FFH
，使得计数100个脉冲时刚好溢出;中断返回PT0D，PT0D跳到MAIN
000BH装载计数初值
