&par Example Description

This demonstration generates a 10 kHz / 50 % PWM signal on TMR1_CH1 (PD1) 
and measures its frequency and duty-cycle with TMR2 in PWM-Input mode (PA1).

TMR2_CC2Isr Function to calculate:
DutyCycle =  (TMR2_CC1*100)/(TMR2_CC2)  %.
Frequency = (RCM_Clocks.HCLK_Frequency/2) / (TMR2_CC2) Hz.
The minimum frequency value to measure is 1 Hz. 

Reminder: When using PA1, ensure that the corresponding jumpers on the J10
header of the TINY board are properly connected.

&par Hardware Description
  - using TMR1 Channel_1 (PD1) to output PWM
  - using TMR2 Channel_2 (PA1) to input PWM
