Changed to standard style format. Text descriptions were clarified and simpli-
fied (eg. DMA operation, FIFO mode vs. Non-FIFO mode operations etc).
Clarified timing diagrams. Renamed Rclk (Receive Clock) to Bclk (Baud
Clock) and timing symbols. Added T
Minor clarifications in text descriptions. Changed A0-A7 in Figures
to A0-A2.
Changed to single column format. Corrected A2 and A0 pin numbers in Pin
Descriptions. Added Device Status to Ordering Information.
markings of "A2 YYWW" and newer have 5V tolerant inputs. Devices with top mark-
ings of "CC YYWW" and older do not have 5V tolerant inputs.
Corrected ordering information. Added third digit to Revision Number.
