Preliminary
Corrected patent number, front page; reference to DAN112; corrected CTS#, DSR#, RI#
and CD# in figure 11 internal loopback; shaded MCR bit-2 and EFR bit-4 in table 11; fixed
“(ISR bit=1)” in figure 12; clarified MCR bits 2 and 6; update 5V electrical characteristics
tables with Icc and Isleep current, and added 3.3V electrical characteristics tables
Deleted ICH and ICL from Electrical tables. Finalized and changed values in 3.3V Electri-
cal table. Corrected spelling. Changed data sheet from Preliminary to Final.
Corrected VIH (2.0 to 2.4V) in DC Electrical Characteristics Tables.
Clarified EECS, PERR# & SERR# hardware pin descriptions, MSR Register and Software
Flow Control Functions. Added Programming Examples to explain unloading receive data
using the Special Receive FIFO Data with Status.
Changed V
PCIClk=2MHz, EXT Clock=2Mhz”. Changed Condition on V
Changed Condition on V
Changed to single column format. Added uarttechsupport e-mail address to last page.
Added Device Status to Ordering Information. Clarified RS485 description. Added
description for PCI Burst Read and PCI Burst Write. Added wake-up indicator to interrupt
source table.
Clarified pin descriptions- changed from using logic 1 and logic 0 to HIGH (VCC) and LOW
(GND) for input and output pin descriptions. The XR17C158 is a 5V Only PCI Octal UART
(removed 3.3V electrical characteristics). For a 3.3V PCI Octal UART, please see the
XR17D158. The Device Revision Register (DREV) has been updated to 0x08 for devices
with top mark date code "H2 YYWW".
The Device Revision Register (DREV) has been updated to 0x09 for devices with top
mark date code "I2 YYWW".
The programming examples to unload data from the special RX FIFO + LSR data register
were updated to use a dummy write to DVID instead of a dummy read to DVID to prevent
the byte swapping in the devices with top mark date code of "GC YYWW" and older.
SEE”PROGRAMMING EXAMPLES” ON PAGE 54.
Updated the 1.4mm-thick Quad Flat Pack package description from "TQFP" to "LQFP" to
be consistent with JEDEC and Industry norms.
