Figure 17. EDSP Control and Status Signals (Stand-along Model)
1. This figure illustrates the EDSP control and status signals in stand-alone mode. All other EDSP and IAFE signals are
connected as shown in
BELB
Setting BELB pin high enables Data Pump to configure in back end loop back. The Data Pump
must be in active state. RDATA and RFP outputs are used in place of the TDATA and TFP inputs,
respectively. TDATA and TFP signals from the external interface are ignored.
Microprocessor (Software) Cntrol
Three primary control pins, CHIPSEL, READ and WRITE, select the Software Mode which also
uses an interrupt output pin to report status changes. Four additional pins are used for the parallel
bus addressing and eight pins for data I/O. Refer to Test Specifications for microprocessor interface
timing in Software Mode.
Chip Select:
The Chip Select (CHIPSEL) pin requires an active low signal to enable Data Pump read or write
operations.
