4.2.2
Pin State and Attach Status Panel
The Pin State & Attach Status section on the right side of the GUI, shown in
Figure 4-4
,
provides a quick graphical status reference and allows physical control pin override.
This section is always displayed.

ALERT# AND A_DET# INDICATORS
When the ALERT# and A_DET# indicators are green, the signals at the device’s
respective pin are low and the corresponding condition has occurred (Alert or Device
attached, respectively). When the indicators are dark, the pin states are high.
4.2.3.2
PIN INDICATORS
The pin indicators (SEL, PWR_EN, M1, M2 and EM_EN) shown in
Figure 4-4
are
green if the signal on the corresponding pin on the UCS1003-1 device is high, and dark
if the signal is low. If the “Pin Ignore” box is checked (see
Section 4.2.3.3 “Pin
Override”
), these indicators will reflect the GUI overrides for these pins.
4.2.3.3
PIN OVERRIDE
For evaluation convenience, the GUI can override the setting of the following pins on
the UCS1003-1 device: PWR_EN, M1, M2 and EM_EN. Check the “Pin Ignore” box
(see
Figure 4-4
) to enable pin override. Then, check in the corresponding pin box to set
the value high.

Note 1:
Pin override does not affect the actual signal on the pin. It only affects the
register values.
2:
The SEL pin is only read once by the UCS1003-1 at power up, so there
is no pin override for it. To close the port power switch, the PWR_EN state
must match the SEL state (e.g., SEL = high and PWR_EN = high).
