BISTEN
TTL In
Built-In Self-Test Enable. When BISTEN is LOW the receiver awaits a D0.0 (sent once per BIST loop)
character and begins a continuous test sequence that tests the functionality of the transmitter, the
receiver, and the link connecting them. In BIST mode the status of the test can be monitored with
Sync and RVS outputs. In normal use BISTEN is held HIGH or wired to V
CC
.
Power for output drivers.
