AT91SAM9XE128/256/512 Preliminary
The PIO lines PA0 to PA31 and PB0 to PB31 and PC0 to PC3 are high-drive current capable.
Each of these I/O lines can drive up to 16 mA permanently with a total of 350 mA on all I/O lines.
Refer to the “DC Characteristics” section of the product datasheet.
The SHDN pin is a tri-state output only pin, which is driven by the Shutdown Controller. There is
no internal pull-up. An external pull-up to VDDBU is needed and its value must be higher than
1 MΩ. The resisitor value is calculated according to the regulator enable implementation and the
SHDN level.
The WKUP pin is an input-only. It can accept voltages only between 0V and VDDBU.
