MMA Note: why you not using directly the UART interface via the USB-Debug-adapter!?
Reply: I tried this in two ways.
1. I used the Tx and Rx pins in the Emulator Board(USB-Debug-adapter) at LK3 and LK5 as the UART pins.Then
Even though I send data to UART, the DR bit LSR register didn't set but UART Transmition is happening.
2. Without using any wires and cables, used that J-Link cable as UART cable because COM port was created to that then both Transmition and Reception not working.
MMA Note: Have you disconnected the appropriate jumpers on the adapter?
Reply: Yes, I disconnected the LK3 and LK5 jumper because those were connected to Tx and Rx pins of UART(P0.1 and P0.2),and I tried to send data to UART then COMRx register fills with the sent data but DR bit in LSR register didn't set but UART Transmition is happening.
