Write Access Code. A write of 0xC5ACCE55 enables
further write access to this device. An invalid write will
have the affect of removing write access.
If LOCKSTATUS[2] is set, then only bits [7:0] of this
register are implemented and lock access is obtained
by consecutively writing 0xC5, 0xAC, 0xCE, 0x55. Bits
[31:8] are unused and any writes to them ignored.
