Function Documentation

uint8_t u8fnConfigPeripheralForMCUModePreset	(	const uint8_t	u8PeripheralIndex,
		const uint8_t	u8ConfigurationIndex
	)

Ties in together a peripheral with a configuration.

Parameters:

None

Returns:

Clear if successful, ME_INVALID_INDEX if passed arguments are out of spec.

uint8_t u8fnCurrentOperationMode

(

void

)

Returns the current operation mode as described by ME_VALID_OP_MODES.

Parameters:

None

Returns:

Operation mode as described by ME_VALID_OP_MODES

uint8_t u8fnInitDefaultOpModes

(

void

)

Configures operation modes according to cau32RunModeConfig, cu32Halt0ModeConfig, and cu32Stop0ModeConfig.

Parameters:

None

Returns:

CLEAR if everything went ok; ME_HW_NOT_READY if in the middle of a transition (command didn't take), or ME_INVALID_RUN_MODE if current mode is not DRUN_MODE.

uint8_t u8fnInitDefaultPeripheralPresets

(

void

)

Loads default configuration for peripheral behavior in different power situations (namely RUN, low power and debug).

Parameters:

None

Returns:

Clear if successful, ME_HW_NOT_READY if there's another operation going on.

Note:

Current implementation only allows for solutions as described in enum ME_PERIPHERAL_PRESETS.

uint8_t u8fnSwitchOpModes

(

const uint8_t

u8Mode

)

Switches from the current operation mode to another one as indicated by the passed argument.

Parameters:

u8Mode,:

Next operation mode index as described by ME_VALID_OP_MODES

Returns:

CLEAR if everything went ok; ME_OP_MODE_CHANGE_DIDNT_OCCUR if we timed-out.
