Description
S’{P4C:+2GNOUS SERIAL DATA ADAPTER (SSDA)
The YlCtiE2 synchronous Serial Data Adap~er provides a bidirec-
iiGna\ jeri~! :r:e:face fcr synchronous dai~ information interchange. It contains in~er+ace logic For simultaneously transmitting and receiving standard syr.chrcnous communications charac~ers in bus organized
sys~ems such as {he bl~CO (Vlicroprocessor systems.
The bus interfzcs of the IMC~52 includes select, enable, read/write,
interrupl, and bus interface logic to allow data transfer over an 8-bit bi-
direc:icnal da(a bus. The parallel data of the bus system is serially
transmitted and received by [he synchronous data interface with syn-
chroniza~ion, iill charac~er insertion/deletion,
and error checking. The
funcitonal configuration of the SSDA is programmed via the data bus
duting system ini~ialization. Programmable contr~l registers provide
control for vatiable word lengths, transmit control, receive control, synchronization control, and interrupt control. Status, t...
