CHAPTER 3

Target interface VCOM

3.3 Target interface VCOM

This J-Link OB model can support virtual COM port (VCOM) as an optional and additional

target interface. For more information about what VCOM is, please refer to

If VCOM (+ optional hardware flow control) support is required on the target hardware to

be designed, the following signals need to be connected:
• TXD (PA9 / Pin 30)

• RXD (PA10 / Pin 31)

• CTS (PA7 / Pin 17)

• RTS (PA6 / Pin 16)
If hardware flow control support is not required, the CTS and RTS signal can be left open.
