Any locations in the range 0x600 to 0x72F not shown above are reserved.
The following sections provide the definitions for the function of each bit within a
register. All registers are configured as 8-bits wide and use the little-endian
numbering convention, i.e. bit 7 is the MSB and bit 0 is the LSB.
NOTE
To mitigate against any changes that may be required to the register set in the future, register access
should ideally be performed using operating system function calls rather than directly.
