5.5.3
HDLC channel 1 offers the flexibility to connect data during certain time slots, as defined
by registers RTR(4:1) and TTR(4:1), to the RFIFO and XFIFO, respectively. Any
combinations of time slots can be programmed for the receive and transmit directions. If
CCR1.EITS = 1 the selected time slots (RTR(4:1)) are stored in the RFIFO of the
signaling controller and the XFIFO contents is inserted into the transmit path as
controlled by registers TTR(4:1).
For HDLC channels 2 and 3, one out of 24 time slots can be selected for each channel,
but in common for transmit and receive direction.
Within selected time slots single bit positions can be masked to be used/not used for
HDLC transmission for all HDLC channels. Additionally, the use of even, odd or both
frames can be selected for each HDLC channel individually.
