Macro

TR Sleep with wake-up on change at dedicated TR pin enabled

Purpose

Put TR into power saving mode and enable wake-up on external event

Syntax

void sleepWOC()

Parameters

 –

Return value

 –

Output values

TR sleeping and waiting for pin change

Preconditions

The same as for iqrfSleep

Remarks

•     Wake-up can be caused on C5 (for TR modules for SIM mounting, e.g. TR-72G) or Q12 (for SMT mounting, e.g.TR-76G) pin change.

•     Both rising and falling edge on the pin is active. The macro can easily be modified in the source code for only one of these edges.

Side effects

•     MCU watchdog is disabled and not reenabled after wake-up.

•     MCU global interrupt is enabled after wake-up.
