J. Radde

Part Number: INA239

Dear T.I. Experts, is it possible to write to more than 1 register while a ChipSelect=Low Period or must CS going high after every Reg.-Write? (Same for Reg.Read?)

Thanks in advance!

Hello,

Thank you for using the TI forum.

Yes, you can leave the chip select low as long as you want for read/write operations. If this will be the only SPI device on your bus, then you can hardware the chip select to low and not even use it. Here is a note about this in the datasheet:
