11.2.2.5 Debug Operation

When run-time debugging, this peripheral will continue normal operation. The SLPCTRL is only affected

by a break in debug operation: If the SLPCTRL is in a sleep mode when a break occurs, the device will

wake up and the SLPCTRL will go to active mode, even if there are no pending interrupt requests.

If the peripheral is configured to require periodical service by the CPU through interrupts or similar,

improper operation or data loss may result during halted debugging.

Functional Description

11.3.1

Initialization

To put the device into a sleep mode, follow these steps:

•

Configure and enable the interrupts that should wake up the device from sleep. Also enable global

interrupts.

Warning: If there are no interrupts enabled when going to sleep, the device cannot wake

up again. Only a reset will allow the device to continue operation.

•

Select the sleep mode to be entered and enable the Sleep Controller by writing to the Sleep Mode

bits (SMODE) and the Enable bit (SEN) in the Control A register (SLPCTRL.CTRLA). A SLEEP

instruction must be run to make the device actually go to sleep.
