AD5432 Reset

Question

Sometimes an AD5432 on our board enters a bad state, means that even if the SPI message is correct (measured with the scope) the output is not. The only solution so far is a power cycle. 
 According to the data sheet there are several op-codes as reserved, maybe one of them acts as a reset? Or does anyone know another way to reset the device after power-up?

Hi, 
 Thanks for providing a sample sequence as it provides a clearer picture of the problem. 
 What do you mean by this sentence? 
 
 This belong to any value sent to the DAC. 
 
 For sequence #3, #4, #6, what is the result if 0x129C is written instead of 0x1808? 
 It would be great if this can be replicated on bench with the digital lines and OP162_OUT captured simultaneously using the sequence you provided. 
 Cheers, 
 Ivan
