LMX2572: Question about writing registers in block mode

Part Number: LMX2572


Hi:

I'm working on the LMX2572 fast hopping mode. I can write those hopping registers in separated SPI cycles, every cycle only writes one register. However, the time cost of writing multiple cycles SPI is pretty significant. In the datasheet, it mentioned in the block mode, I can write multiple registers in one SPI cycle, but the registers have to be continuous in address. In some other chips, we can put different register values together with the address values in one block, and write the entire block in one cycle. The address of those registers doesn't have to be continuous. I tried this mode on LMX2572, but it didn't work. I wonder if it's possible to do this in LMX2572?

Thank you,

Jason
