# Class SnSR Values

## Question

Asked by mmarcial on 2016-08-25 in General.

What would SnSR=0x07 mean?

What would SnSR=0x20 mean?

These values are not defined in w5100.h but I am seeing them when I query the status.

Hi~mmarcia

You read the Sn_SR(0x03 of socket register), right?
In case of W5100,it isn’t exist the 0x07,0x20 in Sn_SR value.
Whether or not you need to confirm exact address.

Best regards,
irina
