11 Timers
11.1 Peripheral Timer/Counters
Three general-purpose timer/counter units are available that can be independently configured to operate in one of
five possible modes. Timer 0 and 1 support all 5 modes of operation and Timer 2 supports PWM and Delta-Sigma
modes only. The timers have the following:

5-bit prescaler, divides system clock by 2
Clocked from internal system clock (16MHz)
16-bit counter, 16-bit Rise and Fall (period) registers
Timer: can generate interrupts off Rise and Fall counts. Can be gated by external signal
Counter: counts number of transitions on external event signal. Can use low-high, high-low or both
transitions
PWM/Single pulse: outputs repeating Pulse Width Modulation signal or a single pulse. Can set period and
mark-space ratio
Capture: measures times between transitions of an applied signal
Delta-Sigma: Return-To-Zero (RTZ) and Non-Return-to-Zero (NRZ) modes
Timer usage of external IO can be controlled on a pin by pin basis
