I've noticed many cases in which the libraries associated with an internal resource, such as the 32 bit timer, also set the appropriate GPIO pins accordingly (ex.: The NXP init_timer32 routine sets the pins for CAP0, MAT0, etc.). If I'm using the timer for a blocking delay or to cause an interrupt, I can use the CAP0, MAT0, etc. - or a subset of these pins - for other GPIO functions, correct? I tested this using these GPIO pins for something else and it seems to work fine. I wanted to make certain I wasn't missing some fine point.

This is a general question, but specifically I'm using the LPC1343.
