22 / 122 page  For the IOx configured with dewetting enabled, every time the IC moves from SLEEP to NORMAL an automatic dewetting is performed. 6.1 Pull-down current programming Pull down current generators are implemented as controlled current generator with back to back diode to avoid damaging when the FlexInput input is being brought below ground. Pull Down current values are reported in Table 10. IOx saturation voltages are reported in Table 11. Table 10. Pull Down Current Symbol Parameter Condition Min Typ Max Unit Pin UBSW = 7.5 V:36 V, VDD5V = 4.85 V:5.15 V, Tj-max = 150 °C unless otherwise specified.
