2.4
2.4.1
The CPU has the internal registers shown in figure 2-4. There are two types of registers: general registers and control
registers.
2.4.2
The CPU has eight 32-bit general registers. These general registers are all functionally alike and can be used as both
address registers and data registers. When a general register is used as a data register, it can be accessed as a 32-bit, 16-bit,
or 8-bit register. When the general registers are used as 32-bit registers or address registers, they are designated by the
letters ER (ER0 to ER7).
The ER registers divide into 16-bit general registers designated by the letters E (E0 to E7) and R (R0 to R7). These
registers are functionally equivalent, providing a maximum sixteen 16-bit registers. The E registers (E0 to E7) are also
referred to as extended registers.
