Maximum total output current through pull up IO has to be limited to 100 mA, that means five IO channels

switched on at the same time with 20 mA nominal current or 10 IO with channels switched on at the same time

with 10 mA nominal current.

This is related to max power dissipation. Maximum junction temperature is of 150 °C.

1. In case of I_pu_0 and I_pu_1, VPUsat max is limited to VPRE-1.5 V because low drop circuit is not

implemented for I_pu_0 and I_pu_1. It means that with UBSW=7.5 V current is guaranteed with VIO <=6 V
