PCI_PRST & DSP_RESET,6412

Hello,

I am using TMS320c6412 and for hardware design I would like to know whether one reset (PCI PRST) needs to occur before another (DSP RESET). If yes, which RESET should happen first.

Is there any relationship between PCI PRST and DSP RESET?? Does PCI PRST has priority over DSP RESET?? For hardware design, shall I look for PCI PRST and based on that do DSP RESET???

Any help is appreciated.

The relationship and behavior of PCI RST and DSP RESET is a bit complicated.
Goto the tms320c6412 product folder at ti.com. There should be a reference to
'TMS320C6000 DSP Peripheral Component Interconnect (PCI) Reference Guide'
that should have the info that you need.
