Bit 7:
Enable Software Interrupt (ENSWINT)
0= Disable. Writing 0s to an INT_CLRx register, when ENSWINT is cleared, causes the corresponding interrupt to clear
1= Enable. Writing 1s to an INT_CLRx register, when ENSWINT is set, causes the corresponding interrupt to post.
1= Enable. Writing 1s to an INT_CLRx register, when ENSWINT is set, causes the corresponding interrupt to post.
