12 Timers
12.1 Peripheral Timer / Counters
Two general-purpose timer / counter units are available that can be independently configured to operate in one of five
modes. The timers have the following features:
?
5-bit prescaler, divides system clock by 2
prescale value
as the clock to the timer (prescaler range is 0 to 16)

Clocked from internal system clock
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

value. For example, a prescale value
a value of 0 leaves the clock unmodified and other values divide it by 2
Figure 26: Timer Unit Block Diagram
The clock source for the timer unit is fed from the 16MHz system clock. This clock passes to a 16-bit prescaler where
prescale
of 2 applied to the 16MHz system clock source results in a timer clock of 4MHz. The value of the prescaler is set
through software.
The counter is optionally gated by a signal on the clock / gate input (TIMxCK_GT). If the gate function is selected the
counter is frozen when the clock/gate input is high.
