Sequence of reading / writing registers in the MFRC522

[jonathan1]

Hi, I am trying to use the MFRC522 from a microcontroller using c language

Searching on the internet I found that most of the already assembled codes and libraries are for arduino or are in c ++,

Reading the data sheet of the chip, I found how the hardware must be modified to use the different interface modes: UART, I2C or SPI,

My query is on which sequence of writing and reading of which registers should be used to achieve read or write cards. Greetings!
