EXAMPLE 15-1: INPUT CAPTURE EXAMPLE CODE
/*
The following code segment initialized the timer and setup the input capture
module.
*/
...
//Initialize timer 2

// Init IC1 module
IC1CON = 0x8081;//Enable Module, use timer 2,
//Capture mode 1 (capture every edge)
...
//Read the capture data if available
int cap_data;
