Bit 6 – QK INT DO REQUEST QuiddiKey Data Out Interrupt
A positive edge has occurred on qk_do_request, which means that a data out transfer is requested via the QK_DOR register.
Bit 5 – QK INT DI REQUEST QuiddiKey Data In Interrupt
A positive edge has occurred on qk_di_request, which means that a data in transfer is requested via the QK_DIR register.
Bit 4 – QK INT REJECTED QuiddiKey Rejected Interrupt
A positive edge has occurred on qk_rejected, which means that a command was rejected.
Bit 3 – QK INT ZEROIZED QuiddiKey Zeroized Interrupt
A positive edge has occurred on qk_zeroized, which means that QuiddiKey has moved to the Zeroized or Locked state.
Bit 2 – QK INT ERROR QuiddiKey Error Interrupt
A positive edge has occurred on qk_error, which means that an operation has failed.
Bit 1 – QK INT OK QuiddiKey OK Interrupt
A positive edge has occurred on qk_ok, which means that an operation successfully completed.
Bit 0 – QK INT BUSY QuiddiKey Busy Interrupt
A negative edge has occurred on qk_busy, which means that an operation has completed.
