8.7.2. Using a GPIO Pad as an interrupt / Wakeup source
GPIO pads used as inputs can also be used as an interrupt source for software. In general,
all GPIO pads can also be used as an interrupt. However, not all GPIO’s can be used as a
wakeup source of the module (wakeup from sleep).
Only the following GPIO’s can be used for waking up the system from sleep:
• GPIO1
• GPIO4
• GPIO5
• GPIO8
8.7.3. Using a GPIO Pad as Output
The GPIO pads, when used as outputs, can drive 1.8V CMOS digital devices or compatible
hardware. When set as outputs, the pads have a push-pull output, and therefore the pull-
up resistor can be omitted.
