How to get the socket status
In order to get the current status of its corresponding sockets, user can monitor its STATUS pin.
There are two pins for this function in WIZ127SR.
One, STATUS1, is pin 12 of JP1 and the other, STATUS2, is pin 7 of JP3.
STATUS1(pin 12 of JP1) pin shares the function of Hardware trigger for configuration of
WIZ127SR.
STATUS1 is operating as input for checking whether user makes to enter it into Hardware
trigger mode during booting of WIZ127SR and after booting, WIZ127SR change STATUS1 pin to
output port and this pin notifies what the current status of UART0’s corresponding socket is.
As this pin operates as output pin, if its value is LOW, its corresponding socket is disconnected.
Otherwise, the connection of the socket is established.
STATUS2 pin is only to notify whether its corresponding socket is connected or not.
The meaning of its signal value is the same to STATUS1.
