HD6852, HD68A52
SSDA (Synchronous Serial Data Adapter)
The HD6852 Synchronous Serial Data Adapter provides a bi·directional serial interface for synchronous data information interchange. It contains interface logic for simultaneously transmitting and receiving standard synchronous communica· tions characters in bus organized systems such as the HMCS6800 Microprocessor systems.
The bus interface of the HD6852 includes select, enable, read/write, interrupt, and bus interface logic to allow data transfer over an 8-bit bi·directional data bus. The parallel data of the bus system is serially transmitted and received by the synchronous data interface with synchronization, fill charar-ter insertion/deletion, and error checking.
