32.5.2 Accumulator (CAU_CAA)
Commands use the CAU accumulator for storage of results and as an operand for the
cryptographic algorithms.
Address: CAU_CAA is E008_1000h base + 1h offset = E008_1001h

32.5.3 General Purpose Register (CAU_CA)
The general purpose register is used in the CAU commands for storage of results and as
operands for the various cryptographic algorithms.
Addresses: CAU_CA0 is E008_1000h base + 2h offset = E008_1002h
CAU_CA1 is E008_1000h base + 3h offset = E008_1003h
CAU_CA2 is E008_1000h base + 4h offset = E008_1004h
CAU_CA3 is E008_1000h base + 5h offset = E008_1005h
CAU_CA4 is E008_1000h base + 6h offset = E008_1006h
CAU_CA5 is E008_1000h base + 7h offset = E008_1007h
CAU_CA6 is E008_1000h base + 8h offset = E008_1008h
CAU_CA7 is E008_1000h base + 9h offset = E008_1009h
CAU_CA8 is E008_1000h base + Ah offset = E008_100Ah
