5.2.10 Interrupt Request Register 1 (IRQ1)
Address: 0F019H
Access: R/W
Access size: 8-bit
Initial value: 00H
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.
