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.
Action to take on LDO4 fault (as well as
generating an interrupt):
00 = ignore
01 = shut down regulator
10 = shut down system
11 = reserved (shut down system)
Reset by state machine. Default held in metal
mask.
Time slot for LDO4 start-up
0000 = Disabled (do not start up)
0001 = Start-up in time slot 1
… (total 14 slots available)
1110 = Start-up in time slot 14
1111 = Start up on entering ACTIVE
Reset by state machine. Default held in metal
mask.
Time slot for LDO4 shutdown.
0000 = Shut down on entering OFF
0001 = Shutdown in time slot 1
…. (total 14 slots available)
1110 = Shutdown in time slot 14
1111 = Shut down on entering OFF
