&par Example Description

This example describes how to use TMR2 Channel_2 (PA1) measure frequency
and duty cycle of external signa. User can view the "DutyCycle" "Frequency"
value through serial termainal.

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.
