LDO1 Enable Configuration (Read-only)
000 = Disabled
001 = Enabled always when BAT/SYS is present
010 = Enabled
at 0% of Boot/POR Process Delay Control
011 = Enabled
at 25% of Boot/POR Process Delay Control
100 = Enabled
at 50% of Boot/POR Process Delay Control
101 = Disabled
110 = Disabled
111 = Controlled by LDO1En[1:0] after 100% of Boot/POR Process Delay Control
LDO1ActDSC
LDO1 Active Discharge Control
0: LDO1 output will be actively discharged only in HardReset mode
1: LDO1 output will be actively discharged in HardReset mode and also when its Enable goes Low
.
The active
discharge circuit will continue to draw additional quiescent current as long at this bit is set to 1, even when the
LDO is disabled. (See EC table.)
LDO1En
[1:0]
LDO1 Enable Configuration (effective only when LDO1Seq = 111)
00 = Disabled
01 = Enabled
10 = Enabled when MPC0 is high (regardless of MPC1)
11 = Enabled when MPC1 is high (regardless of MPC0)
LDO1Mode
LDO1 Mode Control
0 = Normal LDO operating mode
1
=
Load switch mode. FET is either fully ON or OFF depending on state of LDO1En. When FET is ON, the
output is unregulated. This setting is internally latched and can change only when the LDO is disabled.
