Other Parts Discussed in Thread: , LMX2594
I can not read any bits from the MUXout over SPI interface. I can set the register R0 to power up and power down the chip and observe the change in the current draw hence I conclude that the SDI, CSB and SCK are OK.
I'm using LMX2582EVM board connected to a third party module capable of SPI communication through test pads, and a picoscope to monitor the lines.
Here the power up command:
And this is reading register R7:
Any ideas what might be wrong?
