Hi everyone,
regarding to these posts

it inidcates that any amount of bytes above 120 will be split into intervals. My question is whether there exists a flag showing that there is still bytes in the queue that needs to be sent out, which after the last packet should show 0 that indicates all are sent. Any hints would be appreciated, thx.

There's a register that indicates how many bytes are in the FIFO, iirc. Check out the TRM for more information.
