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.
