Bit 4—IRQ4 Interrupt Request (IRQ4R): Indicates whether there is in terrupt request input to
the IRQ4 pin. When edge detection mode is set for IR Q4, an interrupt request is cleared by
clearing the IRQ4R bit.
Bit 4: IRQ4R Description
0 No interrupt request input to IRQ4 pin (Initial value)
1 Interrupt request input to IRQ4 pin
Bit 3—IRQ3 Interrupt Request (IRQ3R): Indicates whether there is in terrupt request input to
the IRQ3 pin. When edge detection mode is set for IR Q3, an interrupt request is cleared by
clearing the IRQ3R bit.
Bit 3: IRQ3R Description
0 No interrupt request input to IRQ3 pin (Initial value)
1 Interrupt request input to IRQ3 pin
Bit 2 — IRQ2 Interrupt Request (IRQ2R): Indicates whether there is interrupt request input to
the IRQ2 pin. When edge detection mode is set for IR Q2, an interrupt request is cleared by
clearing the IRQ2R bit.
Bit 2: IRQ2R Description
0 No interrupt request input to IRQ2 pin (Initial value)
1 Interrupt request input to IRQ2 pin
Bit 1 — IRQ1 Interrupt Request (IRQ1R): Indicates whether there is interrupt request input to
the IRQ1 pin. When edge detection mode is set for IR Q1, an interrupt request is cleared by
clearing the IRQ1R bit.
Bit 1: IRQ1R Description
0 No interrupt request input to IRQ1 pin (Initial value)
1 Interrupt request input to IRQ1 pin
Bit 0 — IRQ0 Interrupt Request (IRQ0R): Indicates whether there is interrupt request input to
the IRQ0 pin. When edge detection mode is set for IR Q0, an interrupt request is cleared by
clearing the IRQ0R bit.
Bit 0: IRQ0R Description
0 No interrupt request input to IRQ0 pin (Initial value)
1 Interrupt request input to IRQ0 pin
