9.4 Interrupts
The following timer sources can generate interrupts:
80
Multifunction Timer Module
•
•
Timer overflow flag (TOF) — The TOF bit is set when the first eight stages of the counter roll over
from $FF to $00. The timer overflow interrupt enable bit, TOIE, enables TOF interrupt requests.
Real-time interrupt flag (RTIF) — The RTIF bit is set when the selected RTI output becomes active.
The real-time interrupt enable bit, RTIE, enables RTIF interrupt requests.
