LDO4 Regulator mode
0 = LDO voltage regulator
1 = Current-limited switch (no voltage regulation,
LDO4_VSEL has no effect)
Reset by state machine. Default held in metal mask.
Enable discharge of LDO4 outputs when LDO4 is
disabled
0 = Enabled - Output to be discharged
1 = Disabled - Output is left floating
Note - if LDO Regulators 1, 2, 3 and 4 are all
disabled, then the outputs will all be discharged,
regardless of the LDOn_OPFLT bit.
LDO4 Regulator output voltage (when LDO4_SWI=0)
1 1111 = 3.3V
… (100mV steps)
1 0000 = 1.8V
0 1111 = 1.65V
… (50mV steps)
0 0000 = 0.9V
Reset by state machine. Default held in metal mask.
LDO3 Hibernate behaviour:
00 = Select voltage image settings
01 = disable output
10 = reserved
11 = reserved
Reset by state machine. Default held in metal
mask.
LDO3 Hibernate signal select
00 = Hibernate register bit
01 = L_PWR1
10 = L_PWR2
11 = L_PWR3
Reset by state machine. Default held in metal
mask.
