Interrupts are controlled by the interrupt controller. The sources to start interrupt exception
handling are external interrupt sources (NMI and IRQ7 to IRQ0) and internal interrupt sources
from the on-chip peripheral modules. NMI is an interrupt with the highest priority. For details, see
section 5, Interrupt Controller.
Interrupt exception handling is conducted as follows:
1. The values in the program counter (PC) and condition code register (CCR) are saved to the
2. A vector address corresponding to the interrupt source is generated, the start address is loaded
4.5
Trap instruction exception handling starts when a TRAPA instruction is executed. Trap instruction
exception handling can be executed at all times in the program execution state.
Trap instruction exception handling is conducted as follows:
1. The values in the program counter (PC) and condition code register (CCR) are saved to the
2. A vector address corresponding to the interrupt source is generated, the start address is loaded
The TRAPA instruction fetches a start address from a vector table entry corresponding to a vector
number from 0 to 3, as specified in the instruction code.
Table 4.3 shows the status of CCR after execution of trap instruction exception handling.
