+1.8V to +5.25V supply for the UART Interface and CBUS group pins (2, 3,
6,7,8,9,10 11, 21, 22, 30,31,32). In USB bus powered designs connect this pin to
3V3OUT to drive out at +3.3V levels, or connect to VCC to drive out at +5V CMOS
level. This pin can also be supplied with an external +1.8V to +2.8V supply in order
to drive out at lower levels. It should be noted that in this case this supply should
originate from the same source as the supply to VCC. This means that in bus
powered designs a regulator which is supplied by the +5V on the USB bus should be
used.
