The serial port of the CH32V208 will lose data when it is received

It may be necessary to increase the receive interrupt priority of the serial port. In addition, according to the description of WCH engineers, if the program runs outside the 128KB address range, the flash will not have zero waits, and the program will run ten times slower, so is there a way to ensure that all related programs involved in interrupts are linked to the 128KB address range
