Overview
Data Sheet Addendum November 1996
DSP32C Digital Signal Processor
Products Affected
This advisory is effective for issue 5 of the DSP32C.
Issue 5 devices are identiļ¬ed by a device code of the form DSP32C-X35 (where X is replaced by R or F).
The design consideration involves external writes to and reads from the parallel data register (PDR) with a system clock greater than 66 MHz.
Problem Resolution
PEN, PWN, and PGN may be synchronized with the DSP clock to eliminate this potential alignment problem.
Figure 1 illustrates a circuit that may be used to synchronize these inputs.
Figure 2 shows the associated timing.
The synchronization circuit delays the rise and fall points of PEN, PWN, and ...
