I/O
PU/–
Receive Multifunction Pins A to C, port 5
Depending on programming of bits PC(1:3).RPC(3:0)
these multifunction ports carry information to the framer
interface or from the framer to the OctalLIU
TM. After
reset these ports are configured to be inputs. With the
selection of the appropriate pin function, the
corresponding input/output configuration is achieved
automatically. Depending on bit DIC3.RESR
latching/transmission of data is done with the rising or
falling edge of FCLKR. If not connected, an internal pull-
up transistor ensures a high input level.
An input function must not be selected twice or more.
Selectable pin functions as described for port 1.
