RXIN of the Ethernet PHY.AnalogIRXIN
37
Positive supply for most of the logic function, including the
processor core and most peripherals. The voltage on this pin is
1.3 V and is supplied by the on-chip LDO. The VDDC pins should
only be connected to the LDO pin and an external capacitor as
specified in Table 23-6 on page 986 .
