Purpose
Synopsis
Parameters
Return Codes One of the following as defined in USRINTSEL:
Configure USER IO as an interrupt source for T0, T1, INT0 or INT1.
void USR_INT_Config (
usr_src: Input parameter
Specifies which USER IO is to be used as the interrupt source. The available
choices (defined in USRINTSRC in api_struct_12.h) are:
Int_select: Input parameter
Selects the interrupt source (defined in USRINTSEL in api_struct_12.h) as:
Enable: Input parameter
If TRUE, enables the selected interrupt source; otherwise, disables it.
EdgeTrigger: Inupt parameter
For INT0 and INT1 only, sets the interrupt to be level (FALSE) or edge (TRUE).
Read the current interrupt settings of the specified USER IO pin.
enum USRINTSEL USR_INT_Read ( enum USRINTSRC usr_src );
usr_src: Input parameter
Corresponding USR pin to read the interrupt setting from.
