Transmit Data Flow
Two different types of frames can be transmitted:
– I-frames and
– transparent frames
as shown below.
Figure 23
Transmit Data Flow of ESCC2
For I-frames (command XIF via CMDR register), the address and control fields are
generated autonomously by the ESCC2 and the data in the XFIFO is entered into the
information field of the frame. This is possible only if the ESCC2 is operated in the
automode.
For transparent frames (command XTF via CMDR register), the address and the control
fields have to be entered in the XFIFO as well. This is possible in all operating modes
and used also in auto-mode for sending U-frames.
Version 2 upward:
If CCR3:XCRC is set, the CRC checksum will not be generated internally. The checksum
has to be provided via the transmit FIFO (XFIFO) as the last two or four bytes. The
transmitted frame will be closed automatically only with a (closing) flag.
Note: The ESCC2 does not check whether the length of the frame, i.e. the number of
bytes, to be transmitted makes sense or not.
