On C6713B silicon revision 2.0 and C6713 silicon revision 1.1, the DSP has a reserved memory range that is
mapped to the internal FIFO of the HPI for EDMA engine usage. This reserved memory range is located at
0x60000000 − 0x7FFFFFFF in the memory map. If CPU code (or a host access) happens to read/write from/to this
memory range, the internal HPI state machine can be corrupted, causing one or more of the following occurrences:
• Host reads/writes through the HPI fail. HPI reads return incorrect data, and/or HPI writes result in incorrect
data being written.
• Host reads/writes through the HPI take an unexpectedly long time. The HRDY signal stays high (not ready)
for an extended period of time.
• HPI locks up. HRDY stays high indefinitely.
