Transmit Direction
General Features
In the transmit direction
– a slot-synchronous transparent data transmission
– a high impedance overwrite for the masked bits in the slot
– a programmable number of programmable fill characters between data
is generated automatically.
Options
The different options for this mode are
– The value of the fill-character can be programmed for FA = 1 in the channel
– The number of inter-data time-fill characters as shown in Figure 33 by choosing
Interrupts
The possible interrupts for this mode in transmit direction are identical to those of HDLC.
(also slot synchronous)
specification. The fill-character (TC) is then programmed in the TFLAG. For FA = 0 the
fill character is FF
all fill/mask bits of the channel are ‘1’) FA must be set to ‘0’.
