Description

@CNflysky

hello,
Some CH32V30x microcontrollers does not have BOOT0 pin with small packages (like CH32V305FBP6).
For what I learnt from datasheet, The FLASH_STATR register in this MCU does not have boot mode controlling bit (like what can be found on CH32X035 series),Is there any way to put the chip into USB ISP mode?
Thanks
