4.2.1 RST/NMI and RSTDVCC/SBWTDIO Pins
The RST/NMI and RSTDVCC/SBWTDIO pins have overlapping function when configured as reset but they are differentiated as shown here:
- Both can be used for the reset function. When both are used as reset, they can be tied together.
- RST/NMI also includes the external NMI function and has a configurable pullup or pulldown when used as reset.
- RSTDVCC/SBWTDIO also includes the SBWTDIO function and has a nonconfigurable pullup when used as reset.
