4.2.14 External Interrupts API – Available with all 73S12xxF Devices
This API allows direct access to the two external interrupt pins (EXT3 and EXT2). These two interrupts
are only available as edge (falling/negative or rising/positive) sensitive. The API includes:

Configure the direction for the USER IO pins.
void USER_IO_ Config ( Unsigned char usrsrc, Unsigned char dir )
usrsrc: Input parameter
Corresponding USR pins to be configured as Input or Output. USRIO 0 through 7
will be configured according to the Dir parameter below.
Dir: Input parameter
Direction value (1=input, 0=output) for the selected pins.
Read the value of the USER IO pins.
void USER_IO_Read ( OUT char *user_dir, OUT char *user_data );
User_dir: Output parameter
Direction value (1=input, 0=output) for the selected pins.
User_data: Output parameter
Value of the corresponding USER IO pins. All outputs will reflect the last value
written.
Write values to selected USER IO pins.
Void USER_IO_Write ( IN char cUserIO, IN char cUserIOselect );
cUserIO: Input parameter
Values to write to selected USER IO pins.
cUserIOselect: Input parameter
configured as an output.
Configure External Interrupt 2.
void INT2_Config ( Unsigned char Enable, Unsigned char Polarity );
A ‘1’ in the corresponding bit will enable writing to that USR pin provided it is
