This register is used to clear the edge software interrupts. An interrupt is

 

 

cleared by writing a one to its clear bit. The clear bits are:

 

 

 

CSW0

Clear software 0 interrupt.

 

 

 

 

 

 

 

CSW1

Clear software 1 interrupt.

 

 

 

 

 

 

 

CSW2

Clear software 2 interrupt.

 

 

 

 

 

 

 

CSW3

Clear software 3 interrupt.

 

 

 

 

 

 

 

CSW4

Clear software 4 interrupt.

 

 

 

 

 

 

 

CSW5

Clear software 5 interrupt.

 

 

 

 

 

 

 

CSW6

Clear software 6 interrupt.

 

 

 

 

 

 

 

CSW7

Clear software 7 interrupt.
