LOCK[7:0]: Write Access Password Entry Code

0xA5 = Write access is allowed on the full register map. CRC on register map values is not calculated

(CRCCFG[15:0] = 0x0000) – default.

Any code, except 0xA5 = Write access, is not allowed on the full register map. Only the LOCK register

is writable. CRC on register map is calculated continuously only when DMCLK is running.
