But in the long turn we should make this interrupt threaded since this delay in interrupt context is way too long.

Before checking PEN UP event, IRQ delays for this amount of time to let FSM stabilize. Previously, with only the TSC driver in IRQ mode, this delay was sufficient. The delay is increased slightly to accomodate if the ADC is also being used simultaneously in continuous mode.
