Power-up and reset sequence

The master reset (MRESET) must be released after the VDD2.5 power supply is stable for

a time interval of 2 ms, which is the start-up time of the main oscillator, as illustrated in

Figure 6.

Internal 2.5 V linear regulator

The internal linear regulator specified in Table 24 provides a regulated 2.5 V power supply

for on-chip AFE, OSCI, PLL, USB PHY, PCIe PHY and SYNTH functional blocks.

The 2.5 V regulator cannot be used to supply external devices.
