Modify code comments AND documentation regarding the location of NO_PORTX_PINCHANGES #9

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 

This is not a formal bug, but an attempt to provide clearer
comments in the code and documentation.

// #define NO_PORTB_PINCHANGES // to indicate that port b will not be used for 
pin change interrupts
// #define NO_PORTC_PINCHANGES // to indicate that port c will not be used for 
pin change interrupts
// #define NO_PORTD_PINCHANGES // to indicate that port d will not be used for 
pin change interrupts

If you define any of the three defines above,
these must be defined in the users code BEFORE
#include <PinChangeInt.h>.

Defining any of the definitions above after including
PinChangeInt.h, will have no effect on the size of the compiled code.

Updated.  Thanks for your suggestion.  Let me know if it's not clear enough.
