1. If Soft Modem or RS-232 functionality is desired, use UARTe/CODEC function and use available
NOTES:
GPIO from this or any other port.
2. Second USB port (USB2) can be configured on PSC3 or on the Ethernet port, but not both locations.
3. PSC3_4 can be configured to be LP_CS6 or an interrupt GPIO, except when PS3 is in USB2 or UART3e modes
In these modes, CS6 is not available.
4. PSC3_5 can be configured to be LP_CS7 or an interrupt GPIO, except when PS3 is in USB2 mode.
In this mode, LP_CS7 is not available.
