Freescale Semiconductor

port in round-robin fashion, based upon the ID of the last master to be granted access. The crossbar provides the following
features:
3 master ports:
— e200z335 core complex Instruction port
— e200z335 core complex Load/Store port
—eDMA
4 slave ports
—FLASH
— calibration bus
—SRAM
— Peripheral bridge A/B (eTPU2, eMIOS, SIU, DSPI, eSCI, FlexCAN, eQADC, BAM, decimation filter, PIT, STM
and SWT)
32-bit internal address, 64-bit internal data paths
1.3.3
eDMA
The enhanced direct memory access (eDMA) controller is a second-generation module capable of performing complex data
movements via 32 programmable channels, with minimal intervention from the host processor. The hardware micro architecture
includes a DMA engine which performs source and destination address calculations, and the actual data movement operations,
along with an SRAM-based memory containing the transfer control descriptors (TCD) for the channels. This implementation
is utilized to minimize the overall block size. The eDMA module provides the following features:
All data movement via dual-address transfers: read from source, write to destination
Programmable source and destination addresses, transfer size, plus support for enhanced addressing modes
Transfer control descriptor organized to support two-deep, nested transfer operations
An inner data transfer loop defined by a “minor” byte transfer count
An outer data transfer loop defined by a “major” iteration count
Channel activation via one of three methods:
— Explicit software initiation
— Initiation via a channel-to-channel linking mechanism for continuous transfers
— Peripheral-paced hardware requests (one per channel)
Support for fixed-priority and round-robin channel arbitration
Channel completion reported via optional interrupt requests
1 interrupt per channel, optionally asserted at completion of major iteration count
Error termination interrupts are optionally enabled
Support for scatter/gather DMA processing
Channel transfers can be suspended by a higher priority channel
1.3.4
Interrupt controller
The INTC (interrupt controller) provides priority-based preemptive scheduling of interrupt requests, suitable for statically
scheduled hard real-time systems. The INTC allows interrupt request servicing from up to 191 peripheral interrupt request
sources, plus 165 sources reserved for compatibility with other family members).
For high priority interrupt requests, the time from the assertion of the interrupt request from the peripheral to when the processor
is executing the interrupt service routine (ISR) has been minimized. The INTC provides a unique vector for each interrupt
request source for quick determination of which ISR needs to be executed. It also provides an ample number of priorities so that
lower priority ISRs do not delay the execution of higher priority ISRs. To allow the appropriate priorities for each source of
interrupt request, the priority of each interrupt request is software configurable.
