# [Chip] Sn_CR don't change the value

## Question

Asked by WIZnet on 2018-07-03 in General.

Sn_CR is designed to be automatically cleared when a value is processed.
What if the value of Sn_CR does not change at all from the value I entered?
Make sure that the ARP packets in the previous packet are working properly.
