1) Incase of SMPS mode, It shall be ensured that the V_DD output pin shall be connected on PCB level to all other V_DD Input
pins.
2) Incase of f_SRI running with max frequency, it shall be ensured that the V_DD operating range is limited to 1.235V upto 1.430V.
The DCDC may be configured in this case with a nominal voltage of 1.33V±7.5%. The static accuracy and regulation
parameter ranges remain also valid for this case.
3) If frequency spreading (SDFREQSPRD = 1) is activated, an additional ripple of 1% need to be considered.
