127 / 923 page  89 5.1.3 Exception Processing Vector Table Before exception processing begins running, the exception processing vector table must be set in memory. The exception processing vector table stores the start addresses of exception service routines. (The reset exception processing table holds the initial values of PC and SP.) All exception sources are given different vector numbers and vector table address offsets, from which the vector table addresses are calculated. During exception processing, the start addresses of the exception service routines are fetched from the exception processing vector table, which indicated by this vector table address. Table 5.3 shows the vector numbers and vector table address offsets. Table 5.4 shows how vector table addresses are calculated. Table 5.3 Exception Processing Vector Table Exception Sources Vector Numbers Vector Table Address Offset Power-on reset PC 0 H'00000000–H'00000003 SP 1 H'00000004–H'00000007 Manual reset PC 2 H'00000008–H'0000000B SP 3 H'0000000C–H'0000000F General illegal instruction 4 H'00000010–H'00000013 (Reserved by system) 5 H'00000014–H'00000017 Slot illegal instruction 6 H'00000018–H'0000001B (Reserved by system) 7 H'0000001C–H'0000001F (Reserved by system) 8 H'00000020–H'00000023 CPU address error 9 H'00000024–H'00000027 DMAC/DTC address error 10 H'00000028–H'0000002B Interrupts NMI 11 H'0000002C–H'0000002F User break 12 H'00000030–H'00000033 (Reserved by system) 13 : 31 H'00000034–H'00000037 : H'0000007C–H'0000007F Trap instruction (user vector) 32 : 63 H'00000080–H'00000083 : H'000000FC–H'000000FF |
