Interrupts
6.1
Introduction
The MPR03X has one interrupt output that is triggered on any touch related event. The interrupts trigger on both the up or down
motion of a finger as defined by a set of configurable thresholds.
6.2
Triggering an Interrupt
An interrupt is asserted any time data changes in the Touch Status Register (Section 5.2). This means that if an electrode touch
or release occurs, an interrupt will alert the application of the change.
6.3
Interrupt Handling
The MPR03X has one interrupt output that is asserted on any touch related event. The interrupts trigger on both the up or down
motion of a finger as defined by a set of configurable thresholds as described in Section 9. To service an interrupt, the application
must read the Touch Status Register (Section 5.2) and determine the current condition of the system. As soon as an I2C read
takes place the MPR03X will release the interrupt.
6.4
IRQ Pin
The IRQ pin is an open-drain latching interrupt output which requires an external pull-up resistor. The pin will latch down based
on the conditions in Section 6.2. The pin will de-assert when an I2C transaction reads from the MPR03X.
