Group power down sequence example 14.6.2.3 Power down delay After a power down sequence is started, the PWRON pin is masked until the sequence is finished and the programmable power down delay is reached, the device can then power up again if a power up event is present. The power down delay time can be programed on OTP via the OTP_PD_SEQ_DLY[1:0] bits. Table 23. Power down delay selection OTP_PD_SEQ_DLY[1:0] Delay after power down sequence 00 No delay 01 1.5 ms 10 5.0 ms 11 10 ms |
