Chapter 5 Sample code
// set P12 as EC0 pin, disable HCLK1
// interval timer, external clock source.
// 8bit mode, output timer00.
// set counter.
// enable output, start timer00.
// set P04 as EC0 pin, disable HCLK1
// interval timer, external clock source.
// 8bit mode, output timer00.
// set counter.
// enable output, start timer00.
//pull low P12 pin
//set P04 as EC0 pin in debug mode
//set P12 as EC0 pin in free run mode
