— 2.5-V SSTL2 compatible I/O
RapidIO interface unit
— 8-bit RapidIO I/O and messaging protocols
— Source-synchronous double data rate (DDR) interfaces
— Supports small type systems (small domain, 8-bit device ID)
— Supports four priority levels (ordering within a level)
— Reordering across priority levels
— Maximum data payload of 256 bytes per packet
— Packet pacing support at the physical layer
— CRC protection for packets
— Supports atomic operations increment, decrement, set, and clear
— LVDS signaling
RapidIO–compliant message unit
— One inbound data message structure (inbox)
— One outbound data message structure (outbox)
— Supports chaining and direct modes in the outbox
— Support of up to 16 packets per message
— Support of up to 256 bytes per packet and up to 4 Kbytes of data per message
— Supports one inbound doorbell message structure
Programmable interrupt controller (PIC)
— Programming model is compliant with the OpenPIC architecture
— Supports 16 programmable interrupt and processor task priority levels
— Supports 12 discrete external interrupts
— Supports 4 message interrupts with 32-bit messages
— Supports connection of an external interrupt controller such as the 8259 programmable
interrupt controller
— Four global high resolution timers/counters that can generate interrupts
— Supports 22 other internal interrupt sources
— Supports fully nested interrupt delivery
— Interrupts can be routed to external pin for external processing
