Access Description
Enable Serial Wire Clock 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.
