Nu-Link2-Me

The Nu-Link2-Me is a debugger and programmer that supports on-line programming and debugging
through SWD interface. The on-board 16 Mbit SPI Flash allows it to off-line program the target
microcontroller. Additionally, the Nu-Link2-Me provides virtual COM port (VCOM) function to print out
messages on PC. Table 2-17 presents how to set the VCOM function by ICESW2.
