8.8 Interrupts

Figure 8-16 shows how the various interrupt sources are multiplexed.

GUID-924B32C4-EE03-4A42-8CC9-08CF78D1716F-low.gif Figure 8-16 External and PIE Interrupt Sources

Eight PIE block interrupts are grouped into one CPU interrupt. In total, 12 CPU interrupt groups, with 8 interrupts per group equals 96 possible interrupts. Table 8-17 shows the interrupts used by 2806x devices.

The TRAP #VectorNumber instruction transfers program control to the interrupt service routine (ISR) corresponding to the vector specified. The TRAP #0 instruction attempts to transfer program control to the address pointed to by the reset vector. The PIE vector table does not, however, include a reset vector. Therefore, the TRAP #0 instruction should not be used when the PIE is enabled. Doing so will result in undefined behavior.

When the PIE is enabled, the TRAP #1 to TRAP #12 instructions will transfer program control to the ISR corresponding to the first vector within the PIE group. For example: the TRAP #1 instruction fetches the vector from INT1.1, the TRAP #2 instruction fetches the vector from INT2.1, and so forth.

GUID-891E738B-6F09-4936-9BA2-1F7221843114-low.gif Figure 8-17 Multiplexing of Interrupts Using the PIE Block

Out of 96 possible interrupts, some interrupts are not used. These interrupts are reserved for future devices. These interrupts can be used as software interrupts if they are enabled at the PIEIFRx level, provided none of the interrupts within the group is being used by a peripheral. Otherwise, interrupts coming in from peripherals may be lost by accidentally clearing their flag while modifying the PIEIFR. To summarize, there are two safe cases when the reserved interrupts could be used as software interrupts:

  1. No peripheral within the group is asserting interrupts.
  2. No peripheral interrupts are assigned to the group (for example, PIE group 7).
