They are cleared upon a power-on reset.Note:The reset of the low-voltage detection reset circuit has no effect on the reset thresholdvoltage settings as the reset cannot clear this register.bit 7 6 5 4 3 2 1 0Field LVRS7 LVRS6 LVRS5 LVRS4 LVRS3 LVRS2 LVRS1 LVRS0Attribute R/W R/W R/W R/W R/W R/W R/W R/WInitial value 0 0 0 0 0 0 0 0bit7:0 Reset threshold voltageDetection voltage (typical value) Release voltage (typical value)Writing "01010101" 2.7 V 2.8 VWriting "01011010" 3 V 3.1 VWriting "10101010" 3.2 V 3.3 VWriting a value other than the above 2.6 V 2.7 V
