IRQ1 is a special function register (SFR) to request an interrupt for each interrupt source.
Each IRQ1 request flag is set to “1” regardless of the IE1 and MIE values when an interrupt is generated. In this case,
an interrupt is requested to the CPU when the related flag of the interrupt enable register (IE1) is set to “1” and the
master interrupt enable flag (MIE) is set to “1”.
By setting the IRQ1 request flag to “1” by software, an interrupt can be generated.
The corresponding flag of IRQ1 is set to “0” by hardware when the interrupt request is accepted by the CPU.

QP00 is the request flag for the input port P00 pin interrupt (P00INT).
QP01 is the request flag for the input port P01 pin interrupt (P01INT).
QP02 is the request flag for the input port P02 pin interrupt (P02INT).
QP03 is the request flag for the input port P03 pin interrupt (P03INT).
QP04 is the request flag for the input port P04 pin interrupt (P04INT).
