I read your code , and find that PA7 is 7, PA20 is 20, PC4 is 68, PD14 is 110, so I guess that PL10 is 362.
I change PA20 to 362, but the code seems to be failed.

Hi, port L have a different address. Registers for port L begin at 0x01C20800. I also create a native driver to the SPI, I2C and UART, but later.
