• 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.

1 VDD = 3.3 V ± 10% / 5.0 V ± 10%, TA = 40 to 125 °C, unless otherwise specified.
2 VDD as mentioned in the table is VDD_HV_A/VDD_HV_B.
3 The configuration PAD3V5 = 1 when VDD = 5 V is only a transient configuration during power-up. All pads but
RESET and Nexus output (MDOx, EVTO, MCKO) are configured in input or in high impedance state.
