# WIZ550web message SW1 and SW2 were pressed

## Question

Asked by DaveOLW on 2015-09-30 in General.

I am getting a message “SW1 and SW2 were pressed”, but they are not, why is this?
As I understand it this is when 3.3 volts are applied to D8 & D9 pins, there is no voltage on these pins. The unit appears to work ok.

[code]Medium Density Flash memory

########## SW1 and SW2 were pressed.
########## Data flash flag was cleared.
########## Please reset a target.

[/code]

What does “Data flash flag was cleared” mean?
It states " Please reset a target, which target, does this mean reset the unit, on reset you get the same message, “SW1 and SW2 were pressed”.

Hi, David.
Digital I/O D8 and D9’s state is declared as an input pin?
This function (Data flash clear) is for data flash using web page storage with FTP server.
Our FTP server in WIZ550web module did not supported ‘DELETE’ function, so users can clear (delete the whole data flash memory) the data flash memory by Switches (D8 & D9). This function can be customized by users.

Thanks.

This is caused by setting pin 8 & 9 to output on the web page I/O configuration.
