I accidentally gave over voltage at one of the input pins of the adc.But some channels of the chip respond correctly when I do a configuration register read and some returns 0xffffff. And the ic respond correctly when i read ID register.How i know the adc is working properly.Does 0xffffff means the register is corrupted.Is there any solution to recover the register.
