Connecting External Debuggers
Even though there is an on-board debugger, external debuggers can be connected directly to ATtiny1607
Curiosity Nano to program/debug the ATtiny1607. The on-board debugger keeps all the pins connected to
the ATtiny1607 and board edge in tri-state when not actively used. Therefore, the on-board debugger will
not interfere with any external debug tools.
