Table 11. Reset Timing Parameters
The supply voltage (VDDIO, and VDDA_3.3) power-up waveform should be monotonic, and the 300s minimum rise time is
from 10% to 90%.
After the de-assertion of reset, it is recommended to wait a minimum of 100s before starting programming on the MIIM
(MDC/MDIO) Interface.
