14.2.3.2
There are ten different timer interrupt flags that cause a timer interrupt whenever they are set and
enabled. The timer interrupt enable bits are located in the timer control register (TCR) and the timer
interrupt flags are located in the timer status registers (TSR1, TSR2). All three interrupts will vector
to the same service routine, whose start address is contained in memory locations $FFF6 and
$FFF7.
