;       sinewave - macro to generate a full cycle sinewave table.
;               If points = 256 and sinewave is ORGed at Y:$100,
;               the sinewave table generated is identical to the
;               DSP56001 Y Data ROM contents.  Note that the base
;               address and memory space must be specified before
;               the macro is called.
