关于DS12C887时序的一个问题

这个AS脚的中文描述是错误的
这是原版英文资料
AS (Address Strobe Input) – A positive going address strobe pulse serves to demultiplex the bus. The
falling edge of AS/ALE causes the address to be latched within the DS12C887. The next rising edge that
occurs on the AS bus will clear the address regardless of whether  CS is asserted. Access commands
should be sent in pairs.
