Hi,
I am using the TPS65381 with the TMS570LS0332. I am using the SPI interface to read and write to the device registers. Reading registers works fine, but I have found that when I write a value to a register, when I read it back it still shows the old value. If I cycle power and then read the register it shows the value I wrote. I have tried this with multiple registers.
Is this normal behavior? Do I need to do some sort of soft reset of the TPS chip after a write?
