Section 5 Exception Handling
When exception handling starts, the CPU operates as follows:
(1)
The initial values of the program counter (PC) and stack pointer (SP) are fetched from the
exception handling vector table (PC and SP are respectively the H'00000000 and H'00000004
addresses for power-on resets and the H'00000008 and H'0000000C addresses for manual resets).
See section 5.1.3, Exception Handling Vector Table, for more information. The vector base
register (VBR) is then initialized to H'00000000, the interrupt mask level bits (I3 to I0) of the
status register (SR) are initialized to H'F (B'1111), and the BO and CS bits are initialized. The BN
bit in IBNR of the interrupt controller (INTC) is also initialized to 0. FPSCR is initialized to
H'00040001 by a power-on reset. The program begins running from the PC address fetched from
the exception handling vector table.
(2)
SR and PC are saved to the stack indicated by R15. In the case of interrupt exception handling
other than the NMI or user break, with usage of the register banks enabled, general registers R0 to
R14, control register GBR, system registers MACH, MACL, and PR, and the vector number of the
interrupt exception handling to be executed are saved to the register banks. In the case of
exception handling due to an address error, bus error, register bank error, NMI interrupt, user
break interrupt, or instruction, saving to a register bank is not performed. When saving is
performed to all register banks, automatic saving to the stack is performed instead of register bank
saving. In this case, an interrupt controller setting must have been made so that register bank
overflow exceptions are not accepted (the BOVE bit in IBNR of the INTC is 0). If a setting to
accept register bank overflow exceptions has been made (the BOVE bit in IBNR of the INTC is
1), register bank overflow exception will be generated. In the case of interrupt exception handling,
the interrupt priority level is written to the I3 to I0 bits in SR. In the case of exception handling
due to an address error or instruction, the I3 to I0 bits are not affected. The start address is then
fetched from the exception handling vector table and the program begins running from that
address.
