Hi all, i am using silicon labs controller 8051F340 in which the TX of serial port is not giving expected data(acknowledgment for received data). instead it is giving some other data. It is happening only in one particular board (other boards are fine) frame: 55 xx xx xx xx xx xx xx xx xx AA frame sent frame expected: 61(01 is appearing).
i have doubt that the register settings of that particular ctrller has been corrupted please give suggestions to make it proper without changing controller.
Thank You
Ok, and how is anyone other than you going to verify that?
This is your board design, in your possession, you should check the continuity of the ground plane/connections.
Assuming a 48-pin part, where pin 7 is ground.
