Notes:
CLK
has to be connected to GND on v1.3 to use the internal clock.Hints:
DCO
pin is an output, keep attention that it is not connected to SDO
, because some mainboards bridge these pins (also called SLP
+ RST
).SD_MODE
pin of the jumper has to be set to GND with a wire (SD_MODE=0).

DCO
pin is an output, keep attention that it is not connected to SDO
, because some mainboards bridge these pins (also called SLP
+ RST
).SD_MODE
pin has an external pull-down resistor (SD_MODE=0).
