3.2 Register Configuration
Figure 3-1 shows the register structure of the CPU. There are two groups of registers: the general
registers and control registers.
3.2.1 General Registers
All the general registers can be used as both data registers and address registers. When used as
address registers, the general registers are accessed as 16-bit registers (R0 to R7). When used as
data registers, they can be accessed as 16-bit registers, or the high and low bytes can be accessed
separately as 8-bit registers.
R7 also functions as the stack pointer, used implicitly by hardware in processing interrupts and
subroutine calls. In assembly-language coding, R7 can also be denoted by the letters SP. As
indicated in figure 3-2, R7 (SP) points to the top of the stack.
