Hi, guys
I meet some issue of MPC8378E DUART interface.
My question:
MPC8378E about DUART, how many size(1 byte?) of the transmit and receive buffer of the DUART?
wait for you reply. Thanks

Solved! Go to Solution.
Have a great day,
In FIFO mode for both transmitter and receiver, the MPC8378 UART has 16-byte FIFOs

Hi
How is the last question, still wait for your reply.
Here I have another question more:
1)for FIFO-mode and none FIFO mode, how to distinguish the FIFO/URBR/UTHR? seems the URBR and UTHR have same offset(0x4500/0x4600).
2)in FIFO mode, is the URBR/UTHR be the come in and go out base address?
3)if there are both send and receive FIFOs, then how is the FIFOs connect to the URBR and UTHR?
Wait for you reply! Thanks!

HI, thanks, I meet another problem:
when the IID3–IID0 is 1100(Character time-out), what's the meaning of this Interrupt Description
No characters were removed from or input to
the receiver FIFO during the last four
character times and at least one character is
in the receiver FIFO.
every time I open duart driver to read the RX buffer in fifo mode, I will flush the RX fifo(write the 0x4602 with 0xC3), how could it can receive one character, it is so strange, would you help this???
Wait for your reply. Thanks.
