2.4 ADDRESSING MODES
I
The addressing mode of an instruction can specify the value of an operand
for an operand that can use one of the numerous defined modes. The (ea)
field. The value in the mode field selects one or a set of addressing modes.
The register field specifies a register for the mode or a submode for modes
that do not use registers.
formats of these instructions include appropriate fields for operands that use
A bit field operand is specified by:
The most significant bit of the base byte is bit field offset 0, the least significant

designation is composed of two 3-bit fields: the mode field and the register
only one addressing mode.
bit of the base byte is bit field offset 7, and the least significant bit of the
previous byte in memory is bit offset - 1 . Bit field offsets may have values
in the range of -231 to 231 - 1 , and bit field widths may range between 1
(with an immediate operand), a register that contains the operand (with the
register direct addressing mode), or how the effective address of an operand
in memory is derived. An assembler syntax has been defined for each ad-
