11.10 I/O Pin
This section discusses specific physical details and configuration possibilities for the I/O pins on the
CC26xx and CC13xx devices.
11.10.1 Physical Pin
The digital I/O driver and receiver is a wide-supply voltage range, bidirectional buffer combining an output
buffer, an input buffer with optional hysteresis, and optional pullup and pulldown circuitry. The I/O has
limited power-management features, including support for wakeup from sleep with core power gated. The
sink and source capability of the pins are symmetrical, as shown in
overview of the analog pin stage. Pullup and pulldown resistances are given in the data sheet.
