Interrupt Request Register 01 (IRQ01)
IRQ01 is a specific function register (SFR) to request interrupts.
The bits are unwriteable when the products do not have the peripheral circuits and they return "0" for reading.
QWDT bit of the IRQ01 register becomes "1" when the non-maskable Watch Dog Timer(WDT) interrupt occurs and the
CPU goes to the inerrupt routine regardless the value of the Master Interrupt Enable flag (MIE bit).
Each request flag of IRQ01 except for the QWDT bit becomes "1" when the interrupt request is generated, regardless of
the values of the interrupt enable register (IE01) and master interrupt enable flag (MIE). At that time, it requests the
interrupt to the CPU if the applicable flag of IE01 is "1" and the CPU accepts the interrupt if the MIE is "1" to goes to
the interrupt routine.
Also, an interrupt can be generated by writing "1" to the request flag of IRQ01. In this case, the CPU goes to the interrupt
routine immedicately after the next one instruction is executed.
The applicable flag of IRQ01 becomes "0" automatically when the interrupt request is accepted by the CPU.
