Each Timer contains a register for the control of interrupts.

Reserved
Autovector. When AVN = 0; the timer interrupt is an autovectored interrupt and the
processor calculates the appropriate vector from a fixed vector table. AVN = 0 is
also the default value. When AVN = 1; the timer interrupt is a vectored interrupt
and the peripheral must provide an 8-bit vectored interrupt.
Reserved
Pending Interrupt Request. This bit is set to a logic 1 when a valid interrupt
request has been detected. It is automatically reset by the interrupt acknowledge
cycle from the CPU. If PIR = 0, there is no pending interrupt request; this is also
the default value. The PIR bit can be reset by software by writing a logic 0 to this
location.
Interrupt Priority Level. These three bits determine the interrupt priority level of the
interrupt requested by the timer. See Table 52.
