EVISION
Removed Preliminary designation.
Changed to standard style format. Text descriptions were clarified and sim-
plified (eg. DMA operation, FIFO mode vs. Non-FIFO mode operations etc).
Corrected RTS Hysteresis character values in
grams. Renamed Rclk (Receive Clock) to Bclk (Baud Clock) and timing
symbols. Added T
Added patent number and updated Block Diagram.
Added and updated device status in Ordering Information.
Changed to standard style format. Clarified sleep mode conditions. Devices
with top mark date code of "F2 YYWW" and newer have 5V tolerant inputs
(except for XTAL1). Devices with top mark date code of "DC YYWW" and
older do not have 5V tolerant inputs.
Updated the 1.4mm-thick Quad Flat Pack package description from "TQFP"
to "LQFP" to be consistent with the JEDEC and Industry norms.
