The LSISAS1064 provides an industry standard UART interface. The
UART performs serial-to-parallel conversion on data characters received
from a peripheral device or modem, and parallel-to-serial conversion on
data characters received from the CPU. The CPU has access to UART
status at any time during functional operation. The status information
includes the type and condition of the transfer operations being
performed by the UART, and any error conditions such as parity, overrun,
framing, or break interrupt.
The LSISAS1064 UART is compatible with the standard 16550 UART,
with the following exceptions:
