Table 14 provides weak pull figures. Both pull-up and pull-down resistances are supported.

•

Table 15 provides output driver characteristics for I/O pads when in SLOW configuration.

•

Table 16 provides output driver characteristics for I/O pads when in MEDIUM configuration.

•

Table 17 provides output driver characteristics for I/O pads when in FAST configuration.
