XR17V358
8
HIGH PERFORMANCE OCTAL PCI EXPRESS UART
REV. 1.0.4
NOTE: Pin type: I=Input, O=Output, IO= Input/output, OD=Output Open Drain, OT=Output Tristate, IS=Input Schmitt
Trigger.
LX
A13
A14
O
Connect these two signals together to external 4.7uH inductor.
FB
C11
I
Connect this signal to other end of external 4.7uH inductor. 47uF capacitor to
GND is also required on this pin.
PWRGD
D13
O
Indicates that 1.2V core has been powered up.
ANCILLARY SIGNALS
RESET#
R2
I
System reset (active low). In normal operation, this signal should be HIGH.
TMRCK
A10
I
16-bit timer/counter external clock input.
EN485#
C10
I
Auto RS-485 mode enable (active low). This pin is sampled during power up,
following a hardware reset (RST#) or soft reset (register RESET). It can be
used to start up all 8 UARTs in the Auto RS-485 Half-Duplex Direction control
mode. The sampled logic state is transferred to FCTR bit-5 in the UART
channel.
ENIR#
B10
I
Infrared mode enable (active low). This pin is sampled during power up, fol-
lowing a hardware reset (RST#) or soft-reset (register RESET). It can be
used to start up all 8 UARTs in the infrared mode. The sampled logic state is
transferred to MCR bit-6 in the UART.
