Table 127. Processing Element Features CAR (PE_FEAT) Field Descriptions

	Bit	Field	Value	Description
	31	BRIDGE		PE can bridge to another interface. Examples are PCI,
				proprietary processor buses, DRAM, etc.
	30	MEMORY		PE has physically addressable local address space and can be
				accessed as an endpoint through non-maintenance (i.e.,
				non-coherent read and write) operations. This local address
				space may be limited to local configuration Registers, or could be
				on-chip SRAM, etc.
	29	PROCESSOR		PE physically contains a local processor or similar device that
				executes code. A device that bridges to an interface that
				connects to a processor does not count (see bit 31).
	28	SWITCH		PE can bridge to another external RapidIO interface. An internal
				port to a local endpoint does not count as a switch port. For
				example, a device with two RapidIO ports and a local endpoint is
				a two port switch, not a three port switch, regardless of the
				internal architecture.
	27–8	Reserved	0	These read-only bits return 0s when read.
	7	FLOW_CONTROL_SUPPORT		PE supports congestion flow control mechanism
			0	PE does not support flow control
			1	PE supports flow control
	6	RETRANSMIT_SUPPRESS		PE supports suppression of error recovery on packet CRC errors.
			0	PE does not support suppression
			1	PE supports suppression
	5	CRF_SUPPORT		This bit indicates PE support for the Critical Request Flow (CRF)
				Function.
			0	PE does not support CRF Function
			1	PE supports CRF Function
	4	LARGE_SUPPORT		Support of common transport large systems.
			0	PE does not support common transport large systems
			1	PE supports common transport large systems
	3	EXTENDED_FEATURES		PE has extended features list; the extended features pointer is
				valid.
