Section 2 CPU
2.4.1
The H8S/2000 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. Figure 2.7 illustrates the
usage of the general registers. When the general registers are used as 32-bit registers or address
registers, they are designated by the letters ER (ER0 to ER7).
When the general registers are used as 16-bit registers, the ER registers are divided 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.
When the general registers are used as 8-bit registers, the R registers are divided into 8-bit general
registers designated by the letters RH (R0H to R7H) and RL (R0L to R7L). These registers are
functionally equivalent, providing a maximum sixteen 8-bit registers.
The usage of each register can be selected independently.
General register ER7 has the function of the stack pointer (SP) in addition to its general-register
function, and is used implicitly in exception handling and subroutine calls. Figure 2.8 shows the
stack.
