bit registers, control registers consisting of one 8-bit register and three 16-bit registers, and special function registers such
as peripheral hardware I/O mode registers.
Remark The CCWs of the control registers are mapped in the special function register (SFR) area.
The processor registers consist mainly of three groups. They are general registers consisting of 8 banks of sixteen 8-
