Address Register Specification: When a general register is used as an address register, the
register is specified by a 3-bit register field (ers or erd).
Data Register Specification: A general register can be used as a 32-bit, 16-bit, or 8-bit data
register.
When used as a 32-bit register, it is specified by a 3-bit register field (ers, erd, or ern).
When used as a 16-bit register, it is specified by a 4-bit register field (rs, rd, or rn). The lower 3
bits of the register field specify the register number. The upper bit is set to 1 to specify an
extended register (En) or cleared to 0 to specify a general register (Rn).
When used as an 8-bit register, it is specified by a 4-bit register field (rs, rd, or rn). The lower 3
bits of the register field specify the register number. The upper bit is set to 1 to specify a low
register (RnL) or cleared to 0 to specify a high register (RnH). The correspondence is shown next.
