SERIAL PERIPHERAL INTERFACE (Cont’d)
10.5.5 Low Power Modes
10.5.6 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.
