Data Sheet
RAC
The HDLC receiver is activated when this bit is set to ’1’. If it is ’0’ the HDLC data is not
evaluated in the receiver.

These bits define the characteristics of the IOM Data Ports (DU, DD). The DIM0 bit
enables/disables the collision detection. The DIM1 bit enables/disables the TIC bus
access. The effect of the individual DIM bits is summarized in table 27.
