6.6 PIO Controller lines

All the I/O lines PA0 to PA31, PB0 to PB31, PC0 to PC23 integrate a programmable pull-up

resistor. Programming of this pull-up resistor is performed independently for each I/O line

through the PIO controllers.

Typical pull-up value is 100 kΩ.

All the I/O lines have schmitt trigger inputs.

6.7 I/O Lines Current Drawing

The PIO lines PA0 to PA3 are high-drive current capable. Each of these I/O lines can drive up to

16 mA permanently.

The remaining I/O lines can draw only 8 mA.

However, the total current drawn by all the I/O lines cannot exceed 300 mA.
