Graphical User Interface Description

Linear regulators can be programmed using the LINEAR sub-tab. It enables the user to control the output voltage

and the start-up sequence of the regulators as well as an option to choose standby and low power mode.

Figure 22. LDO Regulators Tab

The Interrupts tab provides user access to the four interrupt registers in PF0100 functional register map. The user

can choose to read the interrupts by pressing on the “Read Interrupt x” button.

Each interrupt is latched so that even if the interrupt source becomes inactive, the interrupt will remain set until

cleared. Each interrupt can be cleared by writing a "1" to the appropriate bit in the Interrupt Status register. This

will also cause the INTB pin to go high.

Each interrupt can be masked by setting the corresponding mask bit to a 1. As a result, when a masked interrupt

bit goes high, the INTB pin will not go low. A masked interrupt can still be read from the Interrupt Status register.

The sense registers contain status and input sense bits so the system processor can poll the current state of

interrupt sources. They are read only, and neither latched nor clearable.

The user may choose to press the “Poll Interrupt x” control to read the Interrupts tab every 500ms.
