5.1.2
The exception processing sources are detected and begin processing according to the timing
shown in table 5.2.

Interrupts
Instructions
When exception processing starts, the CPU operates as follows:
1. Exception processing triggered by reset:
2. Exception processing triggered by address errors, interrupts and instructions:
46
The initial values of the program counter (PC) and stack pointer (SP) are fetched from the
exception processing vector table (PC and SP are respectively the H'00000000 and
H'00000004 addresses). See section 5.1.3, Exception Processing Vector Table, for more
information. 0 is then written to the vector base register (VBR) and 1111 is written to the
interrupt mask bits (I3–I0) of the status register (SR). The program begins running from the PC
address fetched from the exception processing vector table.
SR and PC are saved to the stack indicated by R15. For interrupt exception processing, the
interrupt priority level is written to the SR’s interrupt mask bits (I3–I0). For address error and
instruction exception processing, the I3–I0 bits are not affected. The start address is then
fetched from the exception processing vector table and the program begins running from that
address.

Timing of Source Detection and Start of Processing
Starts when the RES pin changes from low to high.
Detected when instruction is decoded and starts when the
previous executing instruction finishes executing.
Detected when instruction is decoded and starts when the
previous executing instruction finishes executing.
Starts from the execution of a TRAPA instruction.
Starts from the decoding of undefined code anytime except after
a delayed branch instruction (delay slot).
Starts from the decoding of undefined code placed in a delayed
branch instruction (delay slot) or of instructions that rewrite the
PC.
