my code is written below.i am used "IAR EMBEDDED" software.


In my code SPI_write_byte & SPI_read_byte both function have some problem.i cannot communicate with CAT25256 device.

i have a no idea how SPI resistor & flags are used.


please give a solution for how to communicate with CAT25256. give a reference code for (1)master_initialization(2)mater_write(3)slave_initialization(4)master_read


Please provide any solution so that i can write and read a value for CAT25256 device in proper address.
