IRQR — Interrupt Request Reset Bit
Writing a logic 1 to this write-only bit clears the IRQF bit. Writing a
logic 0 to IRQR has no effect. Reset has no effect on IRQR.
1 = IRQF bit cleared
0 = No effect
4.3.3 Timer Interrupts
The multifunction timer can generate these interrupts:
Timer overflow interrupt
Real-time interrupt
Setting the I bit in the condition code register disables all timer interrupts.
4.3.3.1 Timer Overflow Interrupt
A timer overflow interrupt request occurs if the timer overflow flag (TOF)
becomes set while the timer overflow interrupt enable bit (TOIE) is also
4.3.3.2 Real-Time Interrupt
A real-time interrupt request occurs if the real-time interrupt flag, RTIF,
becomes set while the real-time interrupt enable bit, RTIE, is also set.
