Connecting External Debuggers
Even though there is an on-board debugger, external debuggers can be connected directly to the ATtiny1627
Curiosity Nano to program/debug the ATtiny1627. The on-board debugger keeps all the pins connected to the
ATtiny1627 and board edge in tri-state when not actively used. Therefore, the on-board debugger will not interfere
with any external debug tools.
