Processor PMC (PrPMC) Interface
The PrPMC module is a high-performance, processor-based intelligent controller that can perform the
following functions:
•
On-board system management
•
Board software configuration
•
Board booting control
•
System interrupt handling
•
Interface bridging between the module and the external networking system
•
System operation status report and maintenance
•
Baseband data processing assistance in real time
The PrPMC interface has the following features:
•
Compliant to the following specifications:
— PCI Local Bus Specification (Revision 2.3)
— PCI Bus Power Management Specification (Revision 1.1)
— IEEE1386.1
— ANSI/VITA 32-2003
•
PCI interface:
— 32-bit bus
— 33 MHz/66 MHz
— 3.3V signal only
— Tsi620 internal PCI arbiter
— Tsi620 PCI clock generator performs PCI clocking
— PCI interrupt handler: PrPMC module
— Tsi620 drives reset to PrPMC (PrPMC may issue system reset from PMC_RESETOUT#)
