I have recently written some optimizations for string functions and used x64 Assembly. I am also the first time in this article, so I would like to share with you.
X86: Also known as x32, it indicates the Intel x86 architecture, that is, Intel's 32-bit 80386 assembly instruction set.
X64: EM64T of AMD64 and Intel, excluding IA64. You can search for the differences between the three.
Register changes in x64 compared with x86,
We can see from the figure that the main change in the X64 architec

On R9 (parallel), it's okay if PSB is connected to + 5 V. If you want to switch PSB to the serial port mode again, it will be short-circuited. The consequences can be imagined.
