LM10504EVAL User Guide
LM10504 reads the state of Vselect_B2 and Vselect_B3 pins only during
startup. When LM10504 is using the USB bus as a power supply, pins
Vselect_B2 and Vselect_B3 have no effect on LM10504. User can set
pins in software and then power up LM10504 using an external power
supply. Another way to set pins Vselect_B2 and Vselect_B3 is by using
user connector J1 before powering up the board.

To save power, the device can be placed into sleep mode (DEVSLP) by
asserting the DEVSLP pin high. While in sleep mode, Buck1 and Buck2
are disabled. Buck3’s output voltage is transitioned into PSML as set by
LM10504 register 0X09. The DEVSLP pin is internally pulled down.

Poll pins checkbox
Allows continuous reading of the Interrupt pin state and results of on-
board ADC.

Poll status checkbox
Allows continuous reading of the evaluation chip status register.
Allows continuous reading of the evaluation chip status register.
Auto write checkbox
If this box is checked, any change to registry will be written to the device
immediately. Otherwise, the user must press the Write regs button to
update registers. This way, the user can change values in several registers
and update changes simultaneously.

There is a status bar at the bottom of the screen. It shows whether or
not the connection to the evaluation board is established. (In Figure 2,
the status bar reads ready.)
