SWD或ICE接口包含五个引脚，包括VDD、ICE_DAT、ICE_CLK、n重置和VSS。
Through the SWD or ICE interface, the user can do MCU programming or debugging with the Nu-Link。 Specifically, the nReset pin is used to reset the MCU or initialize SWD and ICE signals。
If the Reset pin is missing, although the system can perform debugging normally, because it has failed to reinitialize SWD and ICE signals, the MCU cannot accept the "whole chip erase" command。 In other words, once the chip is locked, the chip locked state cannot be released through the "whole chip erase"。
