I/O Line Drive Levels
tor from the I/O line to VDDIO. Care should be taken, in particular at reset, as all the I/O lines
default to input with the pull-up resistor enabled at reset.
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 150 mA (100 mA for
AT91SAM7S32/16).
