Electrical Characteristics
Input/Output characteristics
Table 97 shows DC characteristics for inputs. Table 98 shows DC characteristics for
outputs.
Pad pullup and pulldown characteristics
Figure 28 illustrates the characteristics for a pad with internal pullup; Figure 29
illustrates the characteristics for a pad with internal pulldown. See "Pinout detail
tables and signal descriptions," beginning on page 11, for information about which
pins use pullup and pulldown resistors.
