Detailed Description

IMPORTANT NOTE ABOUT lpc11u6x TIMERS
For timer 0 on both the 16-bit and 32-bit timers, the capture functions use index 0 for capture 0 functions and index 2 for capture 1 functions, while timer 1 for both the 16-bit and 32-bit timers uses index 0 and index 1.

Use care when selecting The LPC11U6X User manual is inconsistent in it's designation of capture channels for each timer. See the comments for each function for special handling per timer when dealing with capture channels.
