Core Timer Interrupt
4.10 Core Timer Interrupt
This timer can create two types of interrupts. A timer overflow interrupt
occurs whenever the 8-bit timer rolls over from $FF to $00 and the
enable bit TOFE is set. A real-time interrupt occurs whenever the
programmed time elapses and the enable bit RTIE is set. Either of these
interrupts vectors to the same interrupt service routine, located at the
address specified by the contents of memory locations $3FF6 and
$3FF7.
