LMX2572: SPI transsmision

Marek Czekała

Part Number: LMX2572

Hi Guys!

I have an issue with SPI transsmision:
When I write data to LMX2572 reg by reg. I mean [ADDR][Data_MSB][Data_LSB] then I pull CS hish and after a short delay pull CS low and transmit another 3 Bytes it works perfect. But I wont it to be faster and transsmit for example 9 bytes in a row without pulling CS high.

Is it possible? Because it doesn't works to me.

Regards,
Marek

Hi There,

block programming is supported, please check datasheet section 7.5.4 for details.

Hi,

OK, but in my issue I write to registers that are not succeeding. So I would like to address every register but without toggling CS line. Is it possible?

Hi There,

With block programming, the registers to be written must be in sequence. If not, toggling CSB is required for each register write.
