+ IAP upgrade routine:
+ Support serial port and USB for FLASH burning
+
+ 1. Use the IAP download tool to realize the download PA0 floating (default pull-up input)
+ 2. After downloading the APP, connect PA0 to ground (low level input), and press
+ the reset button to run the APP program.
+ 3. The routine needs to install the CH372 driver.
+ Note: FLASH operation keeps the frequency below 100Mhz, it is recommended that the main
+ frequency of IAP be below 100Mhz
