Table 3-2-1 Interrupt Control Registers
If the interrupt level flag (xxxLVn) is set to "level 3", its vector is disabled, regardless of
interrupt enable flag and interrupt request flag.
Writing to the interrupt control register should be done after that all maskable interrupts are
set to be disabled by the MIE flag of the PSW register.
