REVISION HISTORY
DATE
REVISION
DESCRIPTION
October 2003
Rev 5.00
Changed to standard style single-column format. Text descriptions were clarified and
simplified (eg. DMA operation, FIFO mode vs. Non-FIFO mode operations etc). Clari-
fied timing diagrams. Renamed Rclk (Receive Clock) to Bclk (Baud Clock) and timing
symbols. Added TCS, TRWS and TRST.Renamed FIFORdy register to FSTAT register.
March 2005
Rev 5.0.1
Added separate spec for External Clock Frequency in AC Electrical Characteristics.
August 2005
Rev 5.0.2
Updated the 1.4mm-thick Quad Flat Pack package description from "TQFP" to
"LQFP" to be consistent with JEDEC and Industry norms.
