英语翻译
Port 1 and port 2 are each 8-bit wide and have identical characteristics.Data written to these ports are statically latched and remains unchanged until read.As input port they are non-latching,i.e.inputs must be present until read by an input instruction.Inputs are fully TTL compatible and output will drive one standard TTL load.
Timer/Counter The 8048 contains a counter to aid user in counting external events and generating accurate time delays without placing a burden on the processor for these function.The 8-bit binary counter is presettable and readable with two MOV instructions which transfer the contents of the accumulator to the counter and vice versa.
英语翻译Port 1 and port 2 are each 8-bit wide and have identical
端口1和端口2每个都是8位宽,有相同特征.写入这些端口的数据被静态锁存,也保持不变,直到读取.因为输入端是非闭锁的,也就是说必须要有输入,直到读取输入指令.投入充分TTL兼容和输出,将载入一个标准的TTL负载.
定时器/计数器
8048包含一个计数器来帮助用户计数以处理外部事件,并在不加重那些功能模块负担的情况下生成的延误时间.8位二进制计数器是可调整和可读两种传送指示转移的内容,蓄电池反之亦然.
没学过什么单片机,所以有些地方可以翻的不对,你再核对下吧
