-1 Modes (ADF2:IMS = 0)
Receiver Active
The HDLC receiver is activated when this bit is set to "1".
These bits define the characteristics of the IOM Data Ports (IDP0, IDP1) according to
following tables:
1)
2)
If the TIC bus access handling is not required, i.e. if only one layer-2 device
occupies the D and C/I channel, the TIC bus address should be programmed to
"111" e.g. STCR = 70
This function is only meaningful in test mode (ADF1:TEM = 1) for data transfers
with external layer-1 devices (IBC PEB 2095, IEC PEB 2091).
