39 / 518 page  FALC ®56 PEF 2256 H/E External Signals User’s Manual 39 DS1.1, 2003-10-23 Hardware Description 67 (D6) 68 (A6) 69 (B5) 70 (D5) RPA RPB RBC RPD Receive Multifunction Ports 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 FALC ®56. 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 SIC3.RESR latching/transmission of data is done with the rising or falling edge of SCLKR. The same input function must not be selected twice or more. Selectable pin functions are described below. IPU Synchronous Pulse Receive (SYPR) PC(1:4).RPC(3:0) = 0000 B Together with the values of registers RC(1:0) this signal defines the beginning of time slot 0 on system highway port RDO. Only one multifunction port may be selected as SYPR input. After reset, SYPR of port A is used, the other lines are ignored. SYPR cannot be used in combination with RFM. The pulse cycle is an integer multiple of 125 µs. Table 4 Pin Definitions - System Interface (cont’d) Pin or Ball No. Name Pin Type Buffer Type Function |
