2.4.2
The H8/300H CPU has eight 32-bit general registers. These general registers are all functionally
alike and can be used without distinction between data registers and address 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 as 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.
The R registers divide 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.
Figure 2.4 illustrates the usage of the general registers. The usage of each register can be selected
independently.
