max3100
I have some problems interface with max3100 through SPI. I used SPI of PIC18F4620 to interface with max3100 and connect the pins TX,RX of max 3100 to RX,TX of PIC respectively. I successfully write and read the configuration register. For the write data, I successfully write the first byte of write data 0b10000000 and the return value is 0x42, after that I write 0xA2 but what I received is 0x00. I'm not sure about the Dxt and Dxr in the write command, are they the same? I think that there is something wrong with my crystal, I used 3.6864 crystal with 33pF capacitor. How can I check that the crystal works or not?
