Description
The ST16C2552 (2552) is a dual universal asynchronous receiver and
transmitter (UART). The ST16C2552 is an improved version of the
PC16552 UART. The 2552 provides enhanced UART functions with 16
byte FIFOs, a modem control interface, anddata rates up to 4 Mbps.
Onboard status registers provide the user with error indications and
operational status. System interrupts and modem control features may be
