Table 5–8. PLL Counter Settings
To bypass any of the PLL counters, set the bypass bit to 1. The values on the other bits
are then ignored.
Dynamic Phase Shifting
The dynamic phase shifting feature allows the output phase of individual PLL
outputs to be dynamically adjusted relative to each other and the reference clock
without sending serial data through the scan chain of the corresponding PLL. This
feature simplifies the interface and allows you to quickly adjust t
changing output clock phase shift in real time. This is achieved by incrementing or
decrementing the VCO phase-tap selection to a given C counter or to the M counter.
The phase is shifted by 1/8 the VCO frequency at a time. The output clocks are active
during this phase reconfiguration process.

PLL Scan Chain Bits [0..8] Settings
5–8:
Counter Select. Three bits decoded to select
either the M or one of the C counters for
phase adjustment. One address map to select
all C counters. This signal is registered in the
PLL on the rising edge of SCANCLK.
Selects dynamic phase shift direction; 1= UP,
0 = DOWN. Signal is registered in the PLL on
the rising edge of SCANCLK.
Logic high enables dynamic phase shifting.
Free running clock from core used in
combination with PHASESTEP to enable or
disable dynamic phase shifting. Shared with
SCANCLK for dynamic reconfiguration.
When asserted, it indicates to core logic that
the phase adjustment is complete and PLL is
ready to act on a possible second adjustment
pulse. Asserts based on internal PLL timing.
Deasserts on rising edge of SCANCLK.
