Modes of Operation
4.1
Introduction
MPR03X’s operation modes are Stop, Run1, and Run2. Stop mode is the start-up and configuration mode.
4.2
Stop Mode
In Stop mode, the MPR03X does not monitor any of the electrodes. This mode is the lowest power state.
4.2.1
Initial Power Up
On power-up, the device is in Stop mode, registers are reset to the initial values shown in Table 4, and MPR03X starts in Stop
mode drawing minimal supply current. The user configurable pin IRQ/ELE2 defaults to being the interrupt output IRQ function.
IRQ is reset on power-up, and so defaults to logic high. Since the IRQ is an open-drain output, IRQ will be high impedance.
4.2.2
Stop Mode Usage
In order to set the configuration registers, the device must be in stop mode. This is achieved by setting the EleEn field in the
Electrode Configuration register to zero.
