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.
[Description of Bits]
Note:
When an interrupt is generated by the instruction to write to the interrupt request register (IRQ7) or to the interrupt enable
register (IE7), the the interrupt shift cycle starts after the next 1 instruction is executed.
Initial value
Q16H is the request flag for the time base counter 8 Hz interrupt (T8HINT).
Q2H is the request flag for the time base counter 2 Hz interrupt (T2HINT).
