Power_Wakeup Struct Reference

Detailed Description

Specify the wakeup sources for LPDS and Shutdown.

The wakeup sources for LPDS and Shutdown can be dynamically changed at runtime, via Power_configureWakeup(). The application should fill a structure of this type, and pass it as the parameter to Power_configureWakeup() to specify the new wakeup settings.

wakeupGPIOPadLPDS

uint32_t Power_Wakeup::wakeupGPIOPadLPDS

The GPIO source for wakeup from LPDS.

Only one GPIO {2,4,11,13,17,24,26} can be specified as a wake source for LPDS. The GPIO must be specified as one of the following (as defined in driverlib/prcm.h): PRCM_LPDS_GPIO2, PRCM_LPDS_GPIO4, PRCM_LPDS_GPIO11, PRCM_LPDS_GPIO13, PRCM_LPDS_GPIO17, PRCM_LPDS_GPIO24, PRCM_LPDS_GPIO26

wakeupGPIOEdgeLPDS

uint32_t Power_Wakeup::wakeupGPIOEdgeLPDS

The GPIO trigger type for wakeup from LPDS.

Value can be one of the following (defined in driverlib/prcm.h): PRCM_LPDS_LOW_LEVEL, PRCM_LPDS_HIGH_LEVEL, PRCM_LPDS_FALL_EDGE, PRCM_LPDS_RISE_EDGE

wakeupGPIOFxnLPDS

void(* Power_Wakeup::wakeupGPIOFxnLPDS) (uint_least8_t argument)

Function to be called when the configured GPIO triggers wakeup from LPDS.

During LPDS the internal GPIO module is powered off, and special periphery logic is used instead to detect the trigger and wake the device. No GPIO interrupt service routine will be triggered in this case (even if an ISR is configured, and used normally to detect GPIO interrupts when not in LPDS). This function can be used in lieu of a GPIO ISR, to take specific action upon LPDS wakeup.

A value of NULL indicates no GPIO wakeup function will be called.

An argument for this wakeup function can be specified via wakeupGPIOFxnLPDSArg.

Note that this wakeup function will be called as one of the last steps in Power_sleep(), after all notifications have been sent out, and after pins have been restored to their previous (non-parked) states.

wakeupGPIOFxnLPDSArg

uint_least8_t Power_Wakeup::wakeupGPIOFxnLPDSArg

The argument to be passed to wakeupGPIOFxnLPDS()

wakeupSyncIOPadLPDS

uint32_t Power_Wakeup::wakeupSyncIOPadLPDS

The GPIO source for wakeup from LPDS.

Only one GPIO {2,4,11,13,17,24,26} can be specified as a wake source for LPDS. The GPIO must be specified as one of the following (as defined in driverlib/prcm.h): PRCM_LPDS_GPIO2, PRCM_LPDS_GPIO4, PRCM_LPDS_GPIO11, PRCM_LPDS_GPIO13, PRCM_LPDS_GPIO17, PRCM_LPDS_GPIO24, PRCM_LPDS_GPIO26

wakeupSyncIOEdgeLPDS

uint32_t Power_Wakeup::wakeupSyncIOEdgeLPDS

The GPIO trigger type for wakeup from LPDS.

Value can be one of the following (defined in driverlib/prcm.h): PRCM_LPDS_LOW_LEVEL, PRCM_LPDS_HIGH_LEVEL, PRCM_LPDS_FALL_EDGE, PRCM_LPDS_RISE_EDGE
