i am using CAT5241 -digital POT, when it is first powered on all the four POTs being 0 in some IC 's while other uses value 31 based on my circuit configration . so when does all POT s reset to Zero, and what will will be the contents of DR0 when powered on ??

The Wiper Control Register is a volatile register that loses its contents when the CAT5241: Digital Potentiometer (POT) is powered-down. Although the register is automatically loaded with the value in DR0 upon power-up, this may be different from the value present at power-down. Answered by:
