For cyg_interrupt_configure(...) the documentation and the comments for the *.h declaration of cyg_interrupt_configure simply says argument 'level' sets the trigger to be level or edge, and argument 'up' sets rising/falling edge or high/low level.
The types of 'level' and 'up' are cyg_bool_t, true or false. The text implies that the first item of the 'or' clause represent true and the second item false. Is this correct? It would be a lot clearer if the text stated 'level' is of type cyg_bool_t, true or false. Setting 'level' to true enables level triggering of the interrupt. Setting 'level' to false enables edge triggering of the interrupt. Ditto for 'up'.
