Signal Defination
| Sig Name | Descriptin |
|---|---|
| SWDIO | Data I/O pin -- Use 100K Ohm pull-up resistor to VCC. |
| SWO | Optional trace output pin. |
| SWCLK | Clock pin -- Use 100K Ohm pull-down resistor to GND. |
| VCC | Positive Supply Voltage -- Power supply for JTAG interface drivers. |
| GND | Digital ground. |
SWDIO/SWCLK 都需要上拉来保证稳定状态
