UART Tx Observation

[archansathe]

Hello, I am using MPC5604B. I am continuously transmitting UART frames in polling mode (LINFlex_4) and receiving frame using interrupt mode. Randomly at some time, Tx stops. DTF flag is not set. I can see the data to be sent in BDRL register but it does n

Hi,

please send the code with UART initialization and data sending.

Hello Thanks for reply.
When I dig more in the code, I found Tx is getting stopped because I am getting a software reset. But before reset  I observe lot of unexpected (Data Storage) interrupts are coming. What could be the reasons for these interrupts? When this interrupt occurs?

Hi,

Which bits in LINIER register you have set? Which interrupt flag is set?

Martin
