5.4.7 Minimum External Supply Circuit for Single 5V Supply
The diagram shows the minimum external circuit when using a single 5V supply only.
Switching regulator 0 is used to generate the 3.3V for VCCIO and PLLCLK_VCCIO.
Switching regulator 1 is not used in this example. Therefore, supply port VS1 is not connected.
The high voltage IOs are also not used in this example. Therefore, the three high voltage IO supply ports
VIO1, VIO2, and VIO3 are not connected.
