“双向”指的是加1还是减1操作，可以用语句 if dir=’1’ then … else实现；
“异步清零”指的是只要reset为高电平，立即清零，而不需要等待时钟脉冲（计数脉冲）到来；
“同步时钟使能”是指当enable有效时还不能立即把内部输出值加载到锁存器的数据端，而是需要等到下一个时钟，在时钟信号的控制下再相应。
-" Two-way" means plus or minus 1 operation, with a statement if dir = ' 1 ' then ... to the else realization asynchronous clear " means as long as the reset is high, cleared immediately, without the need to wait for clock pulse (counting pulses) arrival synchronous clock enable " refers to when the enable effective was also unable to immediately internal output value is loaded into the data side of the latch, but need to wait until the next clock under the control of the clock signal Further accordingly.
