MOTOROLA
This section describes the timer interface module (TIM). The TIM is a
2-channel timer:
Figure 11-2
Features of the TIM include:
The TIM module shares pins with two port B input/output (I/O) port pins. The full
names of the TIM I/O pins and generic pin names are listed in

The first channel, channel 0, provides a timing reference with input capture,
output compare, and pulse-width-modulation (PWM) functions.
The second channel, channel 1, provides reduced functionality as it doesn’t
have an external pin.
One input capture/output compare channel:
–
–
Buffered and unbuffered PWM signal generation
Programmable TIM clock input:
–
–
Free-running or modulo up-count operation
Toggle any channel pin on overflow
TIM counter stop and reset bits
