/* Recognition Pattern */
The recognition pattern is: C5h, 3Ah, A3h, 5Ch, C5h, 3Ah, A3h, 5Ch.
The Dobbertin chip requires 64 sequential writes with magic serial data on A0 to unlock it, immediately followed by 64 immediate sequential reads to retrieve the 64-bit time data packet from D0, after which the chip locks itself back into ROM mode.
