在Cy7C65215上怎么切换UART和I2C模式

我想在UART模式（SBC0模式2）和I2C模式（SBC0模式5/6）之间切换。是否有一个命令在运行时切换，还是需要重新编程内部闪存？
如果需要闪存重新编程：
1）闪光灯能经受多少个周期？
2）使用Real/WraveUSER闪存请求（0xe0，0xe1）读取和写入闪存显然是可能的。你能提供一个适合CysB3KIT-03的配置，将SBC0配置从UART模式改为I2C模式吗？

  I would like to switch between UART mode (SBC0 Mode 2) and I2C modes (SBC0 Mode 5/6). Is there a command to switch at runtime, or does it require reprogramming the internal flash?

If flash reprogramming is required:
1) How many cycles does the flash endure?
2) Reading and writing of the flash is apparently possible using the READ/WRITE_USER_FLASH requests, (0xE0, 0xE1). Can you provide a config suitable for the CyUSB3Kit-003, changing the SBC0 config from UART mode to I2C mode?
