CONFIG_SPI_NOR_IDLE_IN_DPD
¶
Use Deep Power-Down mode when flash is not being accessed.
Type: bool
Help¶
Where supported deep power-down mode can reduce current draw to as little as 0.1% of standby current. However it takes some milliseconds to enter and exit from this mode.
Select this option for applications where device power management is not enabled, the flash remains inactive for long periods, and when used the impact of waiting for mode enter and exit delays is acceptable.
Defaults¶
No defaults. Implicitly defaults to n
.
