Instruction Set Introduction
This table lists the CPU registers. It contains the contents of the
HHHHH and SSSS register fields.
Y is permitted only as a destination, not as a source.
Writing word data to the 32-bit Y register clears the Y0 portion.
Note that the C2, C0, D2, and D0 registers are not available within this
field. See the dd register field for these registers
Extension and LS portion of the C and D accumulators.
This register set supplements the DDDDD field.
This set designates registers that are written with signed values when
written with word values.
Y is permitted only as a destination, not as a source.
The registers in this field and SSSS combine to make the DDDDD reg-
ister field.
This set designates registers that are written with unsigned values when
written with word values.
The registers in this field and HHHHH combine to make the DDDDD
register field.
Miscellaneous set of registers that can be placed onto or removed from
the stack 32 bits at a time.
This list supplements the registers in the HHHH.L field, which can also
access the stack via the MOVE.L instruction.
