help
If enabled, chip will try to power down flash as part of esp_light_sleep_start(), which costs
more time when chip wakes up. Can only be enabled if there is no SPIRAM configured.
This option will in fact consider VDD_SDIO auto power value (ESP_PD_OPTION_AUTO) as OFF. Also, it is
possible to force a power domain to stay ON during light sleep by using esp_sleep_pd_config()
function.

help
esp32c3 and esp32s3 will reset at wake-up if GPIO is received a small electrostatic
pulse during light sleep, with specific condition
- GPIO needs to be configured as input-mode only
- The pin receives a small electrostatic pulse, and reset occurs when the pulse
voltage is higher than 6 V
For GPIO set to input mode only, it is not a good practice to leave it open/floating,
The hardware design needs to controlled it with determined supply or ground voltage
is necessary.
This option provides a software workaround for this issue. Configure to isolate all
GPIO pins in sleep state.
config ESP_SLEEP_PSRAM_LEAKAGE_WORKAROUND

depends on SPIRAM
help
When the CS pin of SPIRAM is not pulled up, the sleep current will
increase during light sleep. If the CS pin of SPIRAM has an external
pull-up, you do not need to select this option, otherwise, you
should enable this option.

help
When the CS pin of Flash is not pulled up, the sleep current will
increase during light sleep. If the CS pin of Flash has an external
pull-up, you do not need to select this option, otherwise, you
should enable this option.
