Hi and thank you for your responses.
qhb, I first want to try to solve the problem, if possible. And I think that it is, because as Rodims said, there are other examples of comunication via SPI with an EM4325, despite there isn't any using a PIC.
And Rodims, my older post was also related to this, but the problem was with the PIC, that I couldn't send the bits the way I wanted them to be sent. Concermning the Write Enable Words, I have the EM4325 with all the Write Enable Words to 1, so I should be able to write to the EEPROM. I will now try an other SPI operation, as you pose.
Just so you have it, this is what the different SPI lines look when I try to write some data. The first lines is the chip select, second lines is the clock, third lines is the MOSI (first byte is the SPI write command (0xE8), second byte is the data I want to write (0xAB), and then I send three bytes of dummy data so that the EM4325 can give me a response), and last line is the MISO.
Thank you very much,
