System should access touch detection register when this interrupt is received.
Touch interrupt source needs to be enabled to activate key filter data.
Write ‘1’ to enable interrupt signal from touch event
Write ‘0’ to disable interrupt signal from touch event
This bit needs to be enabled before accessing ratio engine data buffer
Write ‘1’ to enable interrupt signal from ratio engine 2
Write ‘0’ to disable interrupt signal from ratio engine 2
This bit needs to be enabled before accessing ratio engine data buffer
Write ‘1’ to enable interrupt signal from ratio engine 1
Write ‘0’ to disable interrupt signal from ratio engine 1
