IRQ7 is a special function register (SFR) to request an interrupt for each interrupt source.
Each IRQ7 request flag is set to “1” regardless of the IE7 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 (IE7) is set to “1” and the
master interrupt enable flag (MIE) is set to “1”.
By setting the IRQ7 request flag to “1” by software, an interrupt can be generated.
The corresponding flag of IRQ7 is set to “0” by hardware when the interrupt request is accepted by the CPU.

Initial value
Q16H is the request flag for the time base counter 8 Hz interrupt (T16HINT).
Q8H is the request flag for the time base counter 8 Hz interrupt (T8HINT).
Q4H is the request flag for the time base counter 4 Hz interrupt (T4HINT).
Q2H is the request flag for the time base counter 2 Hz interrupt (T2HINT).
