Interrupts
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 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.
4.4 Interrupt Processing
The CPU takes these actions to begin servicing an interrupt:
Stores the CPU registers on the stack in the order shown
Sets the I bit in the condition code register to prevent further
interrupts
Loads the program counter with the contents of the appropriate
interrupt vector locations:
$07FC and $07FD (software interrupt vector)
$07FA and $07FB (external interrupt vector)
$07F8 and $07F9 (timer interrupt vector)
The return-from-interrupt (RTI) instruction causes the CPU to recover
the CPU registers from the stack as shown in Figure 4-3.
