Chapter 5 Interrupt
5.2.14 Interrupt Request Register 5 (IRQ5)
Address: 0F01DH
Access: R/W
Access size: 8-bit
Initial value: 00H
IRQ5 is a special function register (SFR) to request an interrupt for each interrupt source.
Each IRQ5 request flag is set to “1” regardless of the IE3 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 (IE5) is set to “1” and the master
interrupt enable flag (MIE) is set to “1”.
By setting the IRQ5 request flag to “1” by software, an interrupt can be generated.
The corresponding flag of IRQ5 is set to “0” by hardware when the interrupt request is accepted by the CPU.

Note:
Initial value
•
•
When an interrupt is generated by the write instruction to the interrupt request register (IRQ5) or to the interrupt
enable register (IE5), the interrupt shift cycle starts after the next 1 instruction is executed.
IRQ3
R/W
QTM2 (bit 4)
QTM3 (bit 5)
QTM2 is the request flag for the timer 2 interrupt (TM2INT).
QTM3 is the request flag for the timer 3 interrupt (TM3INT).
