Graphical User Interface Description

Proceed by manually writing the desired commands or use the “Command” button to display a graphical command

selector in a new window, as shown in Figure 40.

Figure 40. Command Selector Window

The “Command” window contains a set of commands that are useful for automatically sequencing the PF0100

power supplies, thereby emulating system behavior. The “Command” window is organized in six sections, as

described below:

•

PF0100 - SWITCHING SUPPLIES> place a single script command with the selected buck regulator and the

desired function. The available functions are: mode selection, operating voltage setpoint, standby voltage

setpoint, OFF voltage setpoint, enable current limit and disable current limit. Note that for SW2, SW3A/B

and SW4, the VOLTS RANGE HIGH box need to be checked if the initial power up voltage is set to the high

voltage operating range. If working in the lower voltage range, leave the box unchecked.

•

PF0100 - LINEAR SUPPLIES> places a single script command with the selected LDO regulator and the

desired function. The available functions are: operating voltage setpoint, enable and disable output.

•

PF0100 - SWBST> Permits changing the operating voltage, as well as enabling and disabling the SWBST

output.

•

PROGRAMMER COMMANDS> Enables or disables the 3.3V supply as well as the ~8.0V boost supply on

the KITPF0100EPEVBE. Allows a progressive step-up/step-down of the ~8.0V output and controls the

general purpose output to set the PWRON terminal on the PF0100 high or set the same PWRON terminal

low or toggle a pulse that triggers a PWRON event.

•

OTHER COMMANDS> This section provides access to common instructions initiated by the control MCU.

The possible commands include delay, add separator bar, generic I2C write/read, set GPIO1 and GPIO2

high, low or toggle.

•

LOG COMMAND> provide a log report of the actual status of a specific configuration on the PMIC. Syntax

for the log commands are shown in Table 8.
