1.4.3
Digital functions of mixed signal Pins IO1, IO2, IO3, IO4, IO5, IO6, IO7,
These pins can be configured by the user to be standard CMOS input or outputs.
I/O cells 5, 6 and 7 the pin pairs can be connected to and used individually.
I/O cells 1 through 4 provide pin pairs for differential (complimentary) digital connections
