4.2.3
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).
4.2.4
After reset release, MSTPCR is initialized to H'3FFF and all modules except the DTC enter
module stop mode. Consequently, on-chip supporting module registers cannot be read or written
to. Register reading and writing is enabled when module stop mode is exited.
