&par Example Description

The program to show how to configure the TMR1 peripheral to generate 6 Steps.
In this example, a software COM event is generated each 1 ms.

The TMR1 is configured in Timing Mode, each time a COM event occurs, a new TMR1
configuration will be set in advance.

A  =  Channel 1
A' =  Channel 1N
B  =  Channel 2
B' =  Channel 2N
C  =  Channel 3
C' =  Channel 3N

     | Step1 | Step2 | Step3 | Step4 | Step5 | Step6 |
  A  |   X   |       |       |       |       |   X   |
  A' |       |       |   X   |   X   |       |       |
  B  |       |       |       |   X   |   X   |       |
  B' |   X   |   X   |       |       |       |       |
  C  |       |   X   |   X   |       |       |       |
  C' |       |       |       |       |   X   |   X   |

Display TMR1 waveform by oscilloscope.

&par Hardware Description
