4.3.2
If an interrupt is accepted after a reset but before the stack pointer (SP) is initialized, the PC and
CCR will not be saved correctly, leading to a program crash. To prevent this, all interrupt requests,
including NMI, are disabled immediately after a reset. Since the first instruction of a program is
always executed immediately after the reset state ends, make sure that this instruction initializes
the stack pointer (example: MOV.L #xx: 32, SP).
4.3.3
After reset release, MSTPCR is initialized to H'0FFF and all modules except the DMAC,
EXDMAC and the DTC enter module stop mode.
Consequently, on-chip peripheral module registers cannot be read or written to. Register reading
and writing is enabled when module stop mode is exited.
(1)(3) Reset exception handling vector address (when reset, (1)=H'000000, (3)=H'000002)
(2)(4) Start address (contents of reset exception handling vector address)
(5) Start address ((5)=(2)(4))
(6) First program instruction
Note: * Seven program wait states are inserted.
