REV. 1.0.3
HIGH PERFORMANCE DUAL PCI EXPRESS UART
EEDI
J8
O
Write data to EEPROM device. It is manually accessible thru the Configura-
tion Register REGB.
EEDO
L9
I
Read data from EEPROM device. It is manually accessible thru the Configu-
ration Register REGB.
JTAG SIGNALS

BUCK REGULATOR SIGNALS
ENABLE
C10
I
Connect to VCC to enable buck regulator. Connect to GND to disable buck
regulator.
LX
A9
A10
O
Connect these two signals together to external 4.7uH inductor.
FB
C7
I
Connect this signal to other end of external 4.7uH inductor. 47uF capacitor to
GND is also required on this pin.
PWRGD
D9
O
Indicates that 1.2V core has been powered up.
ANCILLARY SIGNALS
RESET#
J5
I
System reset (active low). In normal operation, this signal should be HIGH.
TMRCK
A6
I
16-bit timer/counter external clock input.
EN485#
C6
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 both 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#
B6
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 both UARTs in the infrared mode. The sampled logic state is
transferred to MCR bit-6 in the UART.
