For More Information On This Product,
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.
