from the data bus or from the internal storage registers. The FCT652T
utilizes GAB and GBA signals to control the transceiver functions.

decoding glitch that occurs in a multiplexer during the transition between
stored and real-time data. A low input level selects real-time data and a high

CPBA), regardless of the select or enable control pins.
The FCT652T consists of a bus transceiver with 3-state D-type flip-flops
SAB and SBA control pins are provided to select either real- time or stored
