I work with I2C-spi bridge . Write command are clear and understandable.

How can I set the read Address for Read Operation ?


For example. I can write to AD9548 the following command.

I2C  0x59(write) 0x03 0x00 0x68 0x00 0x04 (Transaction settings,  I selected AD9548 IC)

I2C  0x59(write) 0x04 0x00 0x00 0x30  (I write to AD9548 at 0x0000 address 0x30 data )


How do I set the address to READ operation and read data from AD9548 from 0x0000 address ?
