I/O FUNCTION
System Reset input – active low, logic level signal. Internally pulled
up to AUXIN. This input is driven by the host system and directly
(*)
affects PERST#. Asserting SYSRST# (logic low) forces PERST# to
assert. RCLKEN is not affected by the assertion of SYSRST#.
Shutdown input – active low, logic level signal. Internally pulled up
to AUXIN. When asserted (logic low), this input instructs the power
(*)
switch to turn off all voltage outputs and the discharge FETs are
activated.

I/O FUNCTION
(*)
W83L351 Series
Standby input – active low, logic level signal. Internally pulled up to
AUXIN. When asserted (logic low) after the card is inserted, this
input places the power switch in standby mode by turning off the
3.3V and 1.5V power switches and keeping the AUX switch on. If
the signal is asserted prior to the card being present, STBY#
places the power switch in OFF Mode by turning off the AUX, 3.3V,
and 1.5V power switches.
A logic level power good (with delay). When powered up, this
output remains asserted (logic level low) until all power rails are
within the tolerance. Once all power rails are within the tolerance
and RCLKEN has been released (logic high), PERST# is deasserted (logic high) after a time delay, as shown in the parametric
table. When powered down, this output is asserted whenever any
of the power rails drops below their voltage tolerance.
The PERST# signal is an output from the host system and an input
to the ExpressCard module. This signal is only used by PCI
Express-based modules and its function is to place the
ExpressCard module in a reset state.
During power up, power down, or whenever power to the
ExpressCard module is not stable or not within voltage tolerance
limits, the ExpressCard standard requires that PERST# be
asserted. As a result, this signal also serves as a power-good
indicator to the ExpressCard module, and the relationship between
the power rails and PERST# are explicitly defined in the
ExpressCard standard.
The host can also place the ExpressCard module in a reset state
by asserting a system reset SYSRST#. This system reset
generates a PERST# signal to the ExpressCard module without
disrupting the voltage rails. This is normally called a warm reset.
However, in a cold start situation, the system reset can also be
used to prolong the assertion time of PERST#.

Card Present input for USB cards. Internally pulled up to AUXIN. A
logic low level on this input indicates that the card present supports
(*)
the USB functions. When a card is inserted, CPUSB# is physically
connected to ground if the card supports USB functions.
Card Present input for PCI Express cards. Internally pulled up to
AUXIN. A logic low level on this input indicates that the card
(*)
present supports the PCI Express functions. When a card is
inserted, CPPE# is physically connected to ground if the card
supports PCI Express functions.

I/O FUNCTION
Reference Clock Enable signal. As an output, it is a logic level
power good to the host (no delay – open drain). As an input, if the
signal is kept inactive (low) by the host, PERST# will be prevented
from being de-asserted. Internally pulled up to AUXIN. This pin
serves both as an input and an output. When powered up, a
discharge FET keeps this signal at a low state as long as any of the
output power rails is out of their tolerance range. Once all output
power rails are within the tolerance, the switch releases RCLKEN,
(*)
/O
allowing it to transit to a high state (internally pulled up to AUXIN).
The transition of RCLKEN from a low to a high state starts an
internal timer for the purpose of de-asserting PERST#. As an input,
RCLKEN can be kept low to delay the start of the PERST# internal
timer. Because RCLKEN is internally connected to a discharge
FET, this pin can only be driven low and should never be driven
high as a logic input. When an external circuit drives this pin low,
RCLKEN becomes an input; otherwise, this pin is an output.
Over current status output (open drain). This pin is an open-drain
output. When any of the three power switches (AUX, 3.3V, and
1.5V) is in an over current condition, OC# is asserted (logic low) by
an internal discharge FET with a deglitch delay. Otherwise, the
discharge FET is open, and the pin can be pulled up to a power
supply through an external resistor.
Switched output that delivers 0V, 3.3V or high impedance to the
