Hi everyone,
I have a PIC12F519 uc based board which works as something like usb device.
It communicates with the main board with 2 ports (RB0/ICSPDAT & RB1/ICSPCLK) and i have watched its' protocol via saleae logic analyzer.
The protocol seems to be I2C but after looking at data it does not have a meaningful protocol.
I checked it as uart protocol and it did not mean anything either.
Here is some pic of the Saleae logic program:

Can anyone suggest which protocol is being used between the boards?
