Address Register Specification: When a general register is used as an address register [@ERn,
@(d:16, ERn), @(d:32, ERn), @ERn+, or @–ERn], 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 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 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). This is shown next.
