Default
Description
0 This is the interval over which the integration is
restarted and must be greater than the
integration count. The interval start counter and
RMS power accumulation is started at the sync
pulse after the programmed delay and every
time the interval counter reaches its limit. Bits
0–15
0 Bits 16–20 of the interval over which the
integration is restarted. (Used in conjunction with
the previous variable.)

65535
32-bit interval timer common to all DUC sync
inputs. This timer may be programmed to any
interval count, and each DUC synchronization
input can select this counter as a source. This
counter increments on every TXCLK rising edge.
Bits 0–15
65535 Bits 16-31 of the above mentioned 32-bit interval
timer.
0 Selects the sync source for the DUC sync
counter.
0 Sets the width of the counter generated sync
pulse in TX clock cycles, from 1 to 256. The
width of this pulse must be long enough to be
captured by the slowest block to use the DUC
counter sync.
0 Selects the sync source for composite power
meter 0.
0 Selects the sync source for composite power
meter 1.
0 Selects the sync source for composite power
meter 2.
0 Selects the sync source for composite power
meter 3.
0 Selects the sync source for the TXSYNC_OUT
pin.
