DSP56800E Core Reference Manual
Extension and LS portion of the C and D accumulators.
This field 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 in this table for these registers
This register set supplements the DDDDD field.
This set designates registers that are written with signed values when
they are 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
they are written with word values.
The registers in this field and in 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 also can
access the stack via the MOVE.L instruction.
