0 denotes two's complement sign or highest magnitude bit. Since phase angles are modulo 2π
and phase accumulator is modulo 2
32, this bit may be regarded as ±π.
Fract. Unsigned Mag./Two's Comp.
Integer Unsigned Magnitude
(RTP = 0)
FM, PM — Frequency Modulation,
Phase Modulation Control
FM and PM is the 2-bit Frequency
Modulation/Phase Modulation
Control that determines one of the
four modes shown in Table 2. When
full-scale is exceeded, the accumulator
will roll over correctly allowing
continuous phase accumulation
through 2
π radians.
OBIQ — Data Input/Output Format
Select
When OBIQ is HIGH, offset binary
format is selected. When OBIQ is
LOW, unsigned format is selected.
OEI — x-coordinate Data Output
Enable
When OEI is LOW, I15-0 is enabled for
data output. When OEI is HIGH, I15-0
is placed in a high-impedance state.

OEQ — y-coordinate Data Output
Enable
When OEQ is LOW, Q15-0 is enabled
for data output. When OEQ is HIGH,
Q15-0 is placed in a high-impedance
state.
