See LPC32x0 User manual for details.
The VDD_IOA, VDD_IOB, VDD_IOC, and VDD_IOD supply domains can be operated at a voltage
independent of the other domains as long as all pins connected to the same peripheral are at the same
voltage level. There are two special cases for determining supply domain voltages (for details see
application note AN10777):
a) Ethernet configured in MII mode: VDD_IOD must be the same as VDD_IOB.
b) UART3 when used with hardware flow control or when sharing an RS-232 transceiver with another
UART: VDD_IOA must be the same as VDD_IOD.
