Serial Wire Data Pin Enable
Enable Serial Wire Data connection to pin. WARNING: When this pin is disabled, the device can no longer be accessed by a debugger.
A reset will set the pin back to a default state as enabled. If you disable this pin, make sure you have at least a 3 second timeout
at the start of you program code before you disable the pin. This way, the debugger will have time to halt the device after a reset
before the pin is disabled.
