Hallo,
auf Github findet man nur folgendes Text eines Users.
The DD-series is a smaller-pincount line; parts are available with 14-32
pins. They've got the MVIO (3 or 4 MVIO pins depending on pincount). The
product brief claims 10 output pins, 11 input pins, on the 14-pin
package. With VDD, VDDIO, and GND. That implies that there will be a way
to configure the UPDI pin to act as an I/O pin, and Reset to act as an
input only if configured appropirately in the fuses. We'll have to wait
until more information is available, but it sounds like the reset pin on
these parts will be the pin that needs the HV pulse (likely)
