13.4.5 Low Power Modes

Mode

WAIT

HALT

Description

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 MCU is woken up by an interrupt with

“exit from Halt mode” capability.

Note: The SPI interrupt events are connected to

the same interrupt vector (see INTERRUPTS

chapter).

They generate an interrupt if the corresponding
