| 3-2 | SHDNZ_CFG[1:0] | R/W | 1h | Shutdown configuration. 0d = DREG is powered down immediately after SHDNZ asserts 1d = DREG remains active to enable a clean shut down until a time-out is reached; after the time-out period, DREG is forced to power off 2d = DREG remains active until the device cleanly shuts down 3d = Reserved |
| 1-0 | DREG_KA_TIME[1:0] | R/W | 1h | These bits set how long DREG remains active after SHDNZ asserts. 0d = DREG remains active for 30 ms (typical) 1d = DREG remains active for 25 ms (typical) 2d = DREG remains active for 10 ms (typical) 3d = DREG remains active for 5 ms (typical) |
