Data Sheet – Operation Modes
9.5 Interrupt Chaining
Every chip contains a configurable gate to combine its own internally generated interrupt signal with a signal applied
externally over the XENINT-pin. The INT-mode register is preset via an OTP register can be overwritten by the SPI
interface.
Case A
Device A is set to mode 0
Device B is set to mode 0
The micro controller recognizes an interrupt if both devices signalize that the computation is finished.
Case B
Device A is set to mode 0
Device B is set to mode 1
The micro controller recognizes an interrupt if one of the two devices signalize that the computation is finished.
