Function
General Purpose Output Low (GPOL), port 1
PC(1:4).RPC(3:0) = 1011
The pin level is set fix to low level.
Loss of Signal Indication Output (LOS), port 1
PC(1:4).RPC(3:0) = 1100
The output reflects the Loss of Signal status as readable in
FRS0.LOS.
Receive TDM System Interface Tristate (RTDMT), port 1
PC(1:4).RPC(3:0) = 1101
Controlling of tristate mode for RDO, RSIG,SCLKR and
RFM. The RTDMT value is logically exored with the register
bit SIC3.RRTRI.
Receive Clock Output (RCLK), port 1
PC(1:4).RPC(3:0) = 1111
Receive clock output RCLK. After reset RCLK is configured
to be internally pulled up weekly. By setting of PC5.CRP
RCLK is an active output.
RCLK source and frequency selection is made by
CMR1.RS(1:0) if GPC6.COMP_DIS = 0
CMR4.RS(2:0) if GPC6.COMP_DIS = 1
Receive Multifunction Pins A to D, port 2
Depending on programming of bits PC(1:4).RPC(3:0) these
multifunction ports carry information to the system interface
or from the system to the QuadLIU
are configured to be inputs. With the selection of the
appropriate pin function, the corresponding input/output
configuration is achieved automatically. Depending on bit
SIC3.RESR latching/transmission of data is done with the
rising or falling edge of SCLKR. If not connected, an internal
pullup transistor ensures a high input level.
The input function must not be selected twice or more.
Selectable pin functions as described for port 1.
Receive Multifunction Pins A to D, port 3
Depending on programming of bits PC(1:4).RPC(3:0) these
multifunction ports carry information to the system interface
or from the system to the QuadLIU
are configured to be inputs. With the selection of the
appropriate pin function, the corresponding input/output
configuration is achieved automatically. Depending on bit
SIC3.RESR latching/transmission of data is done with the
rising or falling edge of SCLKR. If not connected, an internal
pullup transistor ensures a high input level.
The input function must not be selected twice or more.
Selectable pin functions as described for port 1.
