Status registers provide access to a variety of flag
and error bits, which are derived from the various
function blocks. An open drain interrupt output pin is
provided, and is supported by flexible interrupt
reporting and mask options via control register
settings. A master reset input pin is provided for
initialization by a host processor or supervisory

The SRC4382 requires a +1.8V core logic supply, in
addition to a +3.3V supply for powering portions of
the DIR, DIT, and line driver and receiver functions. A
separate logic I/O supply supports operation from
+1.65V to +3.6V, providing compatibility with low
voltage logic interfaces typically found on digital
signal processors and programmable logic devices.
The SRC4382 is available in a lead-free, TQFP-48
package, and is pin- and register-compatible with the
Texas Instruments SRC4392 and DIX4192 products.
