Preliminary
Interrupt System
An interrupt request is serviced by the CPU. Interrupt requests are also called “Service
Requests” because they are serviced by a “Service Provider”, the CPU.
Each peripheral unit in the TC1765 typically generates service requests. Additionally, the
Bus Control Unit, the Debug Unit, the DMA controller, and even the CPU itself can
generate service requests. Several peripheral units are able to generate in parallel to a
service request DMA requests to the DMA Controller.
As shown in Figure 14, each TC1765 unit that can generate service requests is
connected to one or multiple Service Request Nodes (SRN). Each SRN contains a
Service Request Control Register mod_SRCx, where “mod” is the identifier of the
service requesting unit and “x” an optional index. The Interrupt arbitration bus connects
the SRNs with the Interrupt Control Unit, which handles interrupt arbitration among
competing interrupt service requests.
Units which can generate service requests are:
– General Purpose Timer Unit (GPTU) with 8 SRNs
– General Purpose Timer Array (GPTA) with 54 SRNs
– Two High-Speed Synchronous Serial Interfaces (SSC0/SSC1) with 3 SRNs each
– Two Asynchronous/Synchronous Serial Interfaces (ASC0/ASC1) with 4 SRNs each
– TwinCAN controller with 8 SRNs
– Two Analog/Digital Converters (ADC0/ADC1) with 4 SRNs each
– Bus Control Unit (BCU) with 1 SRN
– DMA Controller Processor (DMA) with 8 SRNs
– Central Processing Unit (CPU) with 4 SRNs
– Debug Unit (OCDS) with 1 SRN
– Central Processing Unit (CPU) with 4 SRNs (software activated)
External interrupt inputs in TC1765 are available using the input pins connected to the
General Purpose Timer Unit (GPTU). Each of the seven GPTU I/O pins can be used as
an external interrupt input, using the Service Request Nodes of the GPTU module.
Additionally, such an external interrupt input can also trigger a timer function.
