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[2] is set if a Button event occurred (touch or release if enabled). 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.
