Instruction Fields:
MOTOROLA
Effective Address field—Specifies the base location for the bit field. Only data register
Register field—Specifies the destination data register.
Do field—Determines how the field offset is specified.
Offset field—Specifies the field offset, depending on Do.
Dw field—Determines how the field width is specified.
0 — The offset field contains the bit field offset.
1 — Bits 8 – 6 of the extension word specify a data register that contains the offset;
If Do = 0, the offset field is an immediate operand; the operand value is in the range
If Do = 1, the offset field specifies a data register that contains the offset. The value
0 — The width field contains the bit field width.
1 — Bits 2 – 0 of the extension word specify a data register that contains the width;
of 0 – 31.
is in the range of – 2
