OPERATION
In this section the following nomenclature is used to identify memory map register and bit locations:
(CRn; y
In the text which follows, the first occurrence of a Control Bit, Status Bit or Memory Location will be identified by
the Bit’s Symbol or Memory Location’s name, and the location as described above. Subsequent references to
that entity will not have the location identified. The locations of all Control and Status Bits can be found on
pages 79 and 84.
PRIMARY OPERATING MODES
The PHAST-1 may be operated in any of three Primary Operating Modes (P .O.M.):
The P.O.M. of the device determines the form and content of the information at the Rx and Tx Terminal Ports.
In SONET Mode the Terminal Side information consists of the full SONET Format (TOH and SPE consisting of
POH and Payload). The Control Signals are used to differentiate between the TOH and SPE portions. The Rx
Terminal Port Data, Clock and Control Signals are all outputs. The Tx Terminal Port Data, Clock and Control
Signals are all inputs. When this mode of operation is used, an external source is required to create the Tx Ter-
minal Port Timing and Control signals.
The Terminal Side information in Datacom Mode is the same as for SONET Mode. However, the Control Sig-
nals can be configured to gap out the POH byte times. The Rx Terminal Port Data, Clock and Control Signals
are all outputs. The Tx Terminal Port Clock and Control Signals are outputs and the Data is input. With this
operating mode an external timing generator, for Tx Terminal Port timing and control, is not required.
The Terminal I/O in SPE-only mode consists only of the SPE portion of the SONET signal. The TOH Bytes are
not present. The Rx Terminal Port Data, Clock and Control Signals are all outputs. The Tx Terminal Port Data,
Clock and Control Signals are all inputs. When this mode of operation is used an external source is required to
create the Tx Terminal Port Timing and Control Signals.
In SONET and Datacom modes, the Rx and Tx Terminal Ports can be configured for Serial I/O at 51.84 Mbit/s
or Parallel I/O at either 6.48 Mbyte/s or 19.44 Mbyte/s. When SPE-only Mode is selected, Rx and Tx Terminal
Port operation is restricted to Serial I/O. The controls SPE (CR10; 1FA[H], Bit 7), DATACOM (CR5; 0FD[H], Bit
6) and the Pin MBEI are used to define the P .O.M. Serial or parallel operation is invoked with the control PARA
(CR2; 0FA[H], Bit 6) The interaction of these controls is hierarchical in nature as shown in Table 1.
