Overview
SPC563M64
Doc ID 14642 Rev 6
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.
When multiple tasks share a resource, coherent accesses to that resource need to be
supported. The INTC supports the priority ceiling protocol for coherent accesses. By
providing a modifiable priority mask, the priority can be raised temporarily so that all tasks
which share the resource can not preempt each other.
Multiple processors can assert interrupt requests to each other through software setable
interrupt requests. These same software setable interrupt requests also can be used to
break the work involved in servicing an interrupt request into a high priority portion and a low
priority portion. The high priority portion is initiated by a peripheral interrupt request, but
then the ISR asserts a software setable interrupt request to finish the servicing in a lower
priority ISR. Therefore these software setable interrupt requests can be used instead of the
peripheral ISR scheduling a task through the RTOS.
