ATAM510
Each timer represents a single maskable interrupt source (T0INT and T1INT), the priority of
which can be configured under program control. A Timer 0 interrupt can be caused by any of
three conditions (overflow, compare or end-of-measurement). The associated status register
(T0SR) differentiates between these. A status register is not necessary in Timer 1 as an interrupt
is caused only on a compare condition.
