3 | Reserved | R | 0b | This bit is reserved |
2 | SEQUP | R/W | 0b | Set this bit to 1b to trigger a power-up sequence. This bit is automatically reset to 0b. |
1 | SEQDWN | R/W | 0b | Set this bit to 1b to trigger a power-down sequence. This bit is automatically reset to 0b. |
0 | INSTDWN | R/W | 0b |
Instant shutdown bit
0b = Shutdown follows reverse power-up sequence 1b = All delays are bypassed and all rails are shut down at the same time. |
