Interrupts
Interrupt events
The SPI interrupt events are connected to the same interrupt vector (see Interrupts chapter).
They generate an interrupt if the corresponding Enable Control Bit is set and the interrupt
mask in the CC register is reset (RIM instruction).

No effect on SPI.
SPI interrupt events cause the device to exit from WAIT mode.
SPI registers are frozen.
In HALT mode, the SPI is inactive. SPI operation resumes when the device is
woken up by an interrupt with “exit from HALT mode” capability. The data
received is subsequently read from the SPIDR register when the software is
running (interrupt vector fetching). If several data are received before the
wakeup event, then an overrun error is generated. This error can be detected
after the fetch of the interrupt routine that woke up the Device.
