reset the pin is in the state high impedance.
Data Upstream IOM-2 Interface 4/
Receive Serial Data SACCO Channel B1.
The serial data received on this line is forwarded
into the corresponding HDLC-receive channel.
Data is sampled on the
– falling edge of HDC (CCR2:RDS = 0) or
– rising edge of HDC (CCR2:RDS = 1).
