This is an internal configuration, automatically set based on SPI Flash configuration.

Enable PSRAM halfsleep mode feature to reduce power consumption during light sleep, if the PSRAM used
support halfsleep mode.
When enabled, the PSRAM chip will be configured to enter halfsleep mode (if applicable) before entering
light sleep. This reduces power consumption by:
1. Setting refresh rate to 0.5x
2. Setting PSRAM to halfsleep mode
The PSRAM will automatically exit halfsleep mode after waking up from light sleep.

help
Configure the delay time between waking up PSRAM halfsleep mode and the first access to PSRAM.
Refer to the tXHS parameter in datasheet of the used PSRAM to configure this option.
