C	AArch64 global data cache
EE	AArch64 exception endiannes
I	AArch64 instruction cache
M	AArch64 globally enable MMU

Functions

get	AArch64 Read the raw register contents using the appropriate assembly
read	AArch64 Read the contents of a specific RegisterField. The returned value is already shifted to the right to start at bit 0. This means for a field value stored in the register at bit offset 3, the returned value is already shifted by 3 bits to the right. For example: If register raw value is 0b10110, the returned value for a register field specified as bits[4:3] would be 0b01. No further "masking" or "bit-shift" required
set	AArch64 Write the raw register contents using the appropriate contents
write	AArch64 Update the contents of a register from the RegisterFieldValue given. This will only change the bits the RegisterField definition specifies.
