NOTE

The term ‘OVDD’ in this section refers to the associated supply rail of an

input or output. The association is shown in Table 111.

4.3.1

General Purpose I/O (GPIO) DC Parameters

The parameters in Table 10 are guaranteed per the operating ranges in Table 6, unless otherwise noted.

Table 10 shows DC parameters for GPIO pads, operating at two supply ranges:

•1.1 V to 1.3 V

•

1.65V to 3.1V
