Detailed Description

Function Documentation

◆ pwr_set_mode()

void pwr_set_mode	(	enum pwr_sys_mode	mode,
		uint8_t	smps_level
	)

Set power system based on "System Supply Configurations" table in reference manual.

Parameters

[in]	mode	Mode mapping to a mode in the system configuration. Note special SCU modes.
[in]	smps_level	Optional, only needed if using an EXT_SMPS or SMPS_LDO mode. Provide zero if unused, otherwise SMPS step-down converter voltage output level selection.
