HRDY is Always Driven
Advisory EHPI_7
Revision(s) Affected:
1.0 and 1.1
Details:
HRDY is always driven to the same value as its internal state. This is only a problem when a
single system has devices that have ready signals that are used in conjunction with the DSP’s
HRDY signal. This could include a single system with multiple DSPs using their HRDY signals
in conjunction to signal a master device of their ready status.
Workaround:
Logically AND all ready signals with the DSP’s HRDY signal to generate a valid ready status.
