Hello,

We have one of these: Coreless Transformer Isolated High Side Switch Evaluation Board 2 x 8 Channel 1.2A with ISO1H816G

It takes input over SPI to control output power. It works fine until the system giving it input over SPI is reset. At that point the board does not take any additional input and stays in the state it was before the reset. To make it accept SPI commands it has to be power cycled or a reset has to be done on the common reset line.

It seems to be stuck in whatever state it was before the reset.

After CPU that controls it is power cycled we need to be able to command the board without resetting/power cycling it

Is there a way to do that?
