I am attempting to make use of the PSW pin on the AD7799. The problem I am encountering is after I turn it on, it gets shut off when I try to read or write any register besides the status register or the id register. According to the spec sheet the PSW pin should only be shutoff by the AD7799 when going into powerdown mode. At no time am I doing this. It gets shutoff when just reading a register (except for status & id registers). Please advise.
