All interrupt sources should be disabled before initiating any flash operation.
If an enabled interrupt were to occur during a flash operation, the CPU would
fetch 03FFFh as the address of the interrupt service routine. The CPU would
then execute the JMP PC instruction while BUSY=1. When the flash operation
finished, the CPU would begin executing code at address 03FFFh, not the
correct address for interrupt service routine.
谁能告诉我这段是什么意思有点看不太懂
