— Up to eight-beat burst transfers
— 32-, 16-, and 8-bit port sizes controlled by an on-chip memory controller
— Three protocol engines on a per chip select basis:
— Parity support
— Default boot ROM chip select with configurable bus width (8-, 16-, or 32-bit)
Programmable interrupt controller (PIC)
— Functional and programming compatibility with the MPC8260 interrupt controller
— Support for 8 external and 35 internal discrete interrupt sources
— Support for 1 external (optional) and 7 internal machine checkstop interrupt sources
— Programmable highest priority request
— Four groups of interrupts with programmable priority
— External and internal interrupts directed to host processor
— Redirects interrupts to external INTA pin in core disable mode.
— Unique vector number for each interrupt source
Dual industry-standard I
— Two-wire interface
— Multiple master support
— Master or slave I
— On-chip digital filtering rejects spikes on the bus
— System initialization data optionally loaded from I
DMA controller
— Four independent virtual channels
— Concurrent execution across multiple channels with programmable bandwidth control
— All channels accessible to local core and remote PCI masters
— Misaligned transfer capability
— Data chaining and direct mode
— Interrupt on completed segment and chain
DUART
— Two 4-wire interfaces (RxD, TxD, RTS, CTS)
— Programming model compatible with the original 16450 UART and the PC16550D
Serial peripheral interface (SPI) for master or slave
General-purpose parallel I/O (GPIO)
— 39 parallel I/O pins multiplexed on various chip interfaces
