const LOCK_MODE_DATA_ZONE_NO_CRC: u8 = 0b1000_0001;Expand description
Mode bits for a data-zone lock, with the chip’s CRC verification
disabled. The data zone holds secrets (slots 5, 6, 8 contain hashed
PIN/PUK and the I/O master key) that cannot be read back even with
the data zone unlocked, because every secret-bearing slot has
IsSecret=1. There is therefore no way for the host to compute a
meaningful CRC of what is about to be locked, and no value in asking
the chip to verify one. We rely on the magic-word guard at the USB
layer and the interactive double confirmation in the host CLI.
