General purpose I/O (GPIO) DC parameters

Table 21 shows DC parameters for GPIO pads. The parameters in Table 21 are guaranteed per the

operating ranges in Table 10, unless otherwise noted.

1 Actual working drive level is depend on real design. Please contact crystal vendor for selecting drive level of crystal.
