This example provides a short description of how to use the JTAG IOs as standard GPIOs and gives a configuration sequence. First, the SWJ-DP is disabled. The SWJ-DP pins are configured as output push-pull. Five LEDs connected to the PA.13(JTMS/SWDAT), PA.14(JTCK/SWCLK), PA.15(JTDI), PB.03(JTDO) and PB.04(JTRST) pins are toggled in an infinite loop. Note that once the JTAG IOs are disabled, the connection with the host debugger is lost and cannot be re-established as long as the JTAG IOs remain disabled. To avoid this situation, a specified pin is connected to a push-button that is used to disable or not the JTAG IOs: 1. push-button pressed at reset: JTAG IOs disabled and LED1 turned on 2. push-button not pressed at reset: JTAG IOs unchanged and LED2 turned on Before starting this example, you should disconnect your tool chain debugging probe and run the example in standalone mode. 我英语水平差，翻译不过来，帮忙翻译下，我也正愁这个事呢
