2.2.12. PLL Reconfiguration and Dynamic Phase Shift
M-Series devices support PLL reconfiguration and dynamic phase shift with the following features:
- PLL reconfiguration—I/O PLL can reconfigure the M, N, and C counters.
- Dynamic phase shift—I/O PLL can perform positive or negative phase shift. Able to shift multiple phase steps each time, where one phase step is equal to 1/8 of the VCO period. Dynamic Phase Shifts can only be performed via EMIF Calibration IP.
