Table 17-5. Interrupt Mask 3 (INT_MSK3) [0xDE] [R/W]
Table 17-6. Interrupt Mask 2 (INT_MSK2) [0xDF] [R/W]
Bit 7: Enable Software Interrupt (ENSWINT)
0= Disable. Writing 0s to an INT_CLRx register, when ENSWINT is cleared, will cause the corresponding interrupt to clear
1= Enable. Writing 1s to an INT_CLRx register, when ENSWINT is set, will cause the corresponding interrupt to post.
Bit [6:0]: Reserved
Bit 7: Reserved
