Hi Expert,
We use KL17 SPI interface with SLRC61002HN for the register check. Found that the SPI read is functional, For example,
Read 46h --> Response with 6eh , it matches the external IFSEL1="hi", IFSEL0="lo"
But no matter what command we write, the register seems not functional. For example,
Read 03h --> Response with 05h, then Write 03h 1fh --> Read 03h again, the result is still 05h, not 1fh we expect.
Is any command step we have to follow?
Thanks,
Gilbert
Hi Gilbert,
Would you please refer to 7.4.2 SPI interface of the data sheet http://www.nxp.com/documents/data_sheet/SLRC610.pdf and check if you have implemented the SPI transfer correctly? For example, the NSS control, the address byte setting, read/write timing and byte order, etc.
Have a great day,
Kan
