6.5 Interrupts

Figure 6-23 shows how the various interrupt sources are multiplexed within the 280x devices.

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. On the 280x, 43 of these are used by peripherals as shown in Table 6-28.

The TRAP #VectorNumber instruction transfers program control to the interrupt service routine corresponding to the vector specified. TRAP #0 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, TRAP #0 should not be used when the PIE is enabled. Doing so will result in undefined behavior.

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

(1) Out of the 96 possible interrupts, 43 interrupts are currently used. The remaining 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 (example PIE group 12).
(2) ADCINT is sourced as a logical "OR" of both the SEQ1INT and SEQ2INT signals. This is to support backward compatibility with the implementation found on the TMS320F281x series of devices, where SEQ1INT and SEQ2INT did not exist, only ADCINT. For new implementations, TI recommends using SEQ1INT and SEQ2INT and not enabling ADCINT in the PIEIER register.
