Function Descriptions
Table 151. ITC_ConfigureInterrupt
Notes:
– This function replaces ITC_EXT_ITSensitivity from Library ver1.0
– External Interrupts are masked when an I/O (configured as input interrupt) of the same inter-
– If several input pins of a group connected to same interrupt line are selected simultaneously,
Caution:
– You must refer to the datasheet of the device while selecting the interrupt Pin and the Inter-

rupt sensitivity at that pin. If you select a sensitivity which is not available for that pin, the sen-
sitivity of the pin will not be changed.
1) This option to be used for ST72F62 and ST72F63B devices only.
ITC_ConfigureInterrupt
Void ITC_ConfigureInterrupt(ITC_Port Portx, unsigned
char Pin, ITC_Sensitivity Sensitivity)
Enables the interrupts and also Sets the Interrupt sensitiv-
ity of the selected Port pin.
IT_Portx
x = A, B,C,D, E,F
Pin
This value must be between 0 to 7
IT_EDGE_F_0
Sets the interrupt sensitivity of the selected pin as falling
edge and Low level.
IT_EDGE_R
Sets the interrupt sensitivity of the selected pin as rising
edge only
IT_EDGE_F
Sets the interrupt sensitivity of the selected pin as falling
edge only
IT_EDGE_FR
Sets the interrupt sensitivity of the selected pin as falling
edge and rising edge
IT_EDGE_R_1
Sets the interrupt sensitivity of the selected pin as rising
edge and high level.
IT_DEFAULT
Sets the default sensitivity associated with the device.
None
None
ITC_DisableInterrupt
The Port Pin must be configured in Input Interrupt mode.
