Hello,
My customer is trying to write/read LMX2594 registers via SPI, but it does not go well.
Somehow, all read back values are all zero.
Here some questions from my customer.
Q1:
Though datasheet specifies tECS(min) = 5ns for writing and tECS(min) = 10ns for reading, are there any tECS(max) spec? At my customer board, tECS is hundreds ms. If tECS is quit a lot of time, no SPI access timeout?
Q2:
At my customer board, SCK is not continuous. The SCK is repeated intermittently every 8 clocks as follows. Is this OK or SCK has to be continuous?
Q3:
Could you comment if there are other possible causes?
Best regards,
K.Hirano
