hi all

im using adxl345 via SPI module, and i have a question

i want to write some data to some registers before start reading the accelerometer.

if i want to write (0x0B) to format register (0x31)

im looking in the datasheet and im not understanding the SPI write sequence.

is it 16 or 8 bit sequence?

i should send the address+the data in one signal , that is writing as i mentioned above (0x310B) ???

or should i send first the address (0x3100) then sending data (0x0B00) if im using 16 bit
