Table 17-5. Interrupt Mask 3 (INT_MSK3) [0xDE] [R/W]
Bit # 7 6 5 4 3 2 1 0
Field ENSWINT Reserved
Read/Write R/W – – – – – – –
Default 0 0 0 0 000 0
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.
Bit [6:0]: Reserved
