6 CL_CxINT6 Clears the interrupt pending bit CxINT6.
5 CL_CxINT5 Clears the interrupt pending bit CxINT5.
4 CL_CxINT4 Clears the interrupt pending bit CxINT4.
3 CL_CxINT3 Clears the interrupt pending bit CxINT3.
2 CL_CxINT2 Clears the interrupt pending bit CxINT2.
1 CL_CxINT1 Clears the interrupt pending bit CxINT1.
0 CL_CxINT0 Clears the interrupt pending bit CxINT0.
Note: x = 1 to 3
Remarks: 1. The interrupts CxINT1 to CxINT6 are only generated when the corresponding interrupt
enable bit in the CGIE register is set.
2. The interrupt pending bits must be cleared by software in the interrupt service routine.
Caution: In case the interrupt pending bit is not cleared by software in the interrupt service
routine, no subsequent interrupt is generated anymore.
