Notes:
1. -2
15
denotes two’s complement sign bit.
2. NS denotes negative sign, i.e., ‘1’ negates the number.
3. ±2
0
denotes two’s complement sign or highest magnitude bit – since phase angles are modulo 2
π
and phase accumulator is
modulo 2
32
, this bit may be regarded as +
π
or -
π
.
4. All phase angles are in terms of
π
radians, hence notation “x
π
.”
5. If A
CC
= 00, YPIN(15-0) are “don’t cares.”
