Electrical Characteristics
• IO Sequencer
• Direct memory access (DMA) controller (DMA Engine 2)
— Four independent fully programmable DMA channels
— Concurrent execution across multiple channels with programmable bandwidth control
— Misaligned transfer capability for source/destination address
— Data chaining and direct mode
— Interrupt on completed segment, error, and chain
• DUART
— Supports 2 DUART
— Each has two 2-wire interfaces (RxD, TxD)
– The same can be configured as one 4-wire interface (RxD, TxD, RTS, CTS)
— Programming model compatible with the original 16450 UART and the PC16550D
• Serial peripheral interface (SPI)
— Master or slave support
• Power managemnt controller (PMC)
— Supports core doze/nap/sleep/ power management
— Exits low power state and returns to full-on mode when
– The core internal time base unit invokes a request to exit low power state
– The power management controller detects that the system is not idle and there are
outstanding transactions on the internal bus or an external interrupt.
• Parallel I/O
— General-purpose I/O (GPIO)
– 56 parallel I/O pins multiplexed on various chip interfaces
– Interrupt capability
• System timers
— Periodic interrupt timer
— Software watchdog timer
— Eight general-purpose timers
• Real time clock (RTC) module
— Maintains a one-second count, unique over a period of thousands of years
— Two possible clock sources:
– External RTC clock (RTC_PIT_CLK)
– CSB bus clock
• IEEE Std. 1149.1™ compliant JTAG boundary scan
