1.2 Data Memory Organization
Data memory is composed of Special Function Registers and General Purpose Registers.
The General Purpose Registers are accessed either directly or indirectly through the FSR register.
The Special Function Registers are registers used by the CPU and peripheral functions to control the operation of
the device.
