The Growth Detect circuitry outputs a two bit value that
signifies the amount of growth on the data in the CMAC and
Complex Accumulator. Its output, DET0-1, is encoded as
shown in Table 5. If PEAK is low, the highest value of
DET0-1 is latched in the Growth Detect Output Register.
The relative weighting of the bits at the inputs and outputs of
the CMAC is shown in Figure 3. Note that the binary point of
the sine, cosine, RIN and IIN is to the right of the most
significant bit, while the binary point of RO and IO is to the
right of the fifth most significant bit. These CMAC external
input and output busses are aligned with each other to
facilitate cascading NCOMs for FFT applications.
