Hi,

We intended to configure CY7C65213  as self-powered mode. Other than the schematic connection shown below, the datasheet also says

"Using the configuration utility, the configuration descriptor in the
CY7C65213/CY7C65213A flash should be updated to indicate
that it is self-powered."

My question is: Can the internal flash be accessed and set after the circuit is connected this way? Especially the default power mode in the flash is bus-powered. Thanks.

How does the power mode in the flash affect the chip behavior? Is it just for information purpose, or it changes the chip's function?
