Hello all,
I am trying to write a Linux driver for TRF7961. I would like to know if the SPI read/write diagram from page 41 of the datasheet describes the default steps to communicate with the RFID chip? Does this mean that I have to change the SPI mode (clock polarity) between write and read? My master is a i.MX27 chip and changing the SPI mode is "kind of" difficult.
Also, I am interested in the default values of the registers for TRF7961. Where could I find this information?
Thank you in advance for your help.
