27.3.3 Interrupts
| Name | Vector Description | Conditions |
|---|---|---|
| NMI | Non-Maskable Interrupt | CRC failure |
When the interrupt condition occurs the OK flag in the Status (CRCSCAN.STATUS)
register is cleared to ‘0’.
A Non-Maskable Interrupt (NMI) is enabled by writing a ‘1’ to
the respective Enable (NMIEN) bit in the Control A (CRCSCAN.CTRLA) register, but can only
be disabled with a System Reset. An NMI is generated when the OK flag in the CRCSCAN.STATUS
register is cleared, and the NMIEN bit is ‘1’. The NMI request remains
active until a System Reset and cannot be disabled.
An NMI can be triggered even if interrupts are not globally enabled.
