IRQR — Interrupt Request Reset Bit
The multifunction timer can generate these interrupts:
Setting the I bit in the condition code register disables all timer interrupts.
A timer overflow interrupt request occurs if the timer overflow flag (TOF)
becomes set while the timer overflow interrupt enable bit (TOIE) is also
set. See
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.
See
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.
