SERIAL PERIPHERAL INTERFACE (Cont’d)
10.4.6 Low Power Modes
10.4.7 Interrupts
Note: 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).
Mode
Description
WAIT
No effect on SPI.
SPI interrupt events cause the device to exit from WAIT mode.
HALT
SPI registers are frozen.
In HALT mode, the SPI is inactive. SPI operation resumes when the MCU 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 wake-up event, then an
overrun error is generated. This error can be detected after the fetch of the interrupt routine that woke up the
device.
