6.4 Status Registers
The delay between the actual event and the flags indicating the interrupt source may be one scan period.
IrqSrc[6] is set once NVM burn procedure is completed.
IrqSrc[5] is set once SPM write is effective.
IrqSrc[4] is set if a GPI edge as programmed in GpioInterrupt occurred. GpiStat shows the detailed status of the
GPI pins.
IrqSrc[3] is set if a Wheel event occurred (touch, release, rotation clockwise, rotation counter clockwise or position
change) . CapStatMsb, WhlPosMsb and WhlPosLsb show the detailed status of the Wheel.
IrqSrc[2] is set if a Button event occurred (touch or release if enabled). CapStatMsb and CapStatLsb show the
detailed status of the Buttons.
IrqSrc[1] is set once compensation procedure is completed either through automatic trigger or via host request.
IrqSrc[0] is set when actually entering Active or Doze mode either through automatic wakeup or via host request.
CompOpmode shows the current operation mode.

these bits is set.
More than one bit can be
set.
Reading IrqSrc clears it
together with INTB.
