Hi lyz,
A1. When test that example, the chip is secured after reset.(notice "Un-securing the MCU using backdoor key access") When you want to connect it, mass erase will blank the chip, no code in the chip will cause periodic resets.
A2. FTFC->FCCOB[3] point to FCCOB0 which used to fill with Flash command(You can refer to the source code of AN5401SW\3_Basic_operations)
