Power Management

Some flash devices can be put into ultra low power mode; these functions only have an effect if the flash driver supports this feature. Typically any internal RAM buffer is lost while in low power mode.

The power management functions allow the developer to put the flash chip into an ultra low power mode (and take it out of that mode) when it is known the system is going to be idle for a short while. Do not over-use these functions because to restore the previous RAM buffer state typically requires a page to be read.

Note: These functions are only available if the F_LOW_POWER option is enabled.

The functions are the following:

Function Description
f_enter_low_power() Enters low power mode.
f_exit_low_power() Leaves low power mode.
