Interrupt Request Register 67 (IRQ67)
IRQ67 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.
Each request flag of IRQ67 except for the QWDT bit becomes "1" when the interrupt request is generated, regardless of
the values of the interrupt enable register (IE67) and master interrupt enable flag (MIE). At that time, it requests the
interrupt to the CPU if the applicable flag of IE67 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 IRQ67. In this case, the CPU goes to the interrupt
routine immedicately after the next one instruction is executed.
The applicable flag of IRQ67 becomes "0" automatically when the interrupt request is accepted by the CPU.
