User’s Manual
The following Sections give Examples of Typical Transmit Situations for the
Individual Modes
Variable Size Frame Oriented Protocols (HDLC, TMB, TMR)
Normal operation, handling of frame end (FE) indication and hold (H) indication.
Note: 1. FNUM0 must be set to zero.
2. Flag = 7E
3. After sending the FNUM2 – 1 IC characters the device starts polling the hold bit
IC = 7E
in the transmit descriptor once for each further sent IC character. It also rereads
the pointer to the next transmit descriptor once with each poll of the hold
indication. The pointer to the next transmit descriptor can be changed while
HOLD = 1 is set. The value of the pointer, (read in the poll where HOLD = 0) is
used as the next descriptor address. If more than 6 IC characters will be sent,
the use of the Transmit Hold (TH) should be considered as an alternative to
using the descriptor hold bit. See Chapter 5.3.2.
