3.2.2
Immediately after a reset, if an interrupt is accepted before the stack pointer (SP) is initialized, PC
and CCR will not be pushed onto the stack correctly, resulting in program runaway. To prevent
this, immediately after reset exception handling all interrupts are masked. For this reason, the
initial program instruction is always executed immediately after a reset. This instruction should
initialize the stack pointer (e.g. MOV.L #xx: 32, SP).
