-// This example blinks the Picoboard LED when the BOOTSEL button is pressed.
-//
-// Picoboard has a button attached to the flash CS pin, which the bootrom
-// checks, and jumps straight to the USB bootcode if the button is pressed
-// (pulling flash CS low). We can check this pin in by jumping to some code in
-// SRAM (so that the XIP interface is not required), floating the flash CS
-// pin, and observing whether it is pulled low.
-//
-// This doesn't work if others are trying to access flash at the same time,
-// e.g. XIP streamer, or the other core.
