Expand description
Random command.
Returns 32 cryptographically random bytes from the chip’s hardware RNG.
The default mode 0x00 updates the chip’s internal seed before
generating the output, which is what we always want for production use.
Mode 0x01 skips the seed update and exists only for development.
