DC-DC3 Clock Phase Control
0 = Normal
1 = Inverted
DC-DC3 ON Voltage select
DC3_ON_VSEL[6:0] selects the DC-DC3 output
voltage from 0.85V to 3.4V in 25mV steps.
DC3_ON_VSEL[6:2] controls the voltage in 100mV
steps.
DC3_ON_VSEL[6:0] is coded as follows:
00h = 0.85V
01h = 0.875V
…
65h = 3.375V
66h to 7Fh = 3.4V
DC-DC3 Output Capacitor
00 = 10uF to 20uF
01 = 10uF to 20uF
10 = 22uF to 45uF
11 = 47uF to 100uF
LDO2 ON Slot select
000 = Do not enable
001 = Enable in Timeslot 1
010 = Enable in Timeslot 2
011 = Enable in Timeslot 3
100 = Enable in Timeslot 4
101 = Enable in Timeslot 5
110 = Controlled by Hardware Enable 1
111 = Controlled by Hardware Enable 2
LDO2 ON Voltage select
0.9V to 1.6V in 50mV steps
1.7V to 3.3V in 100mV steps
00h = 0.90V
01h = 0.95V
…
0Eh = 1.60V
0Fh = 1.70V
…
1Eh = 3.20V
1Fh = 3.30V
LDO1 ON Slot select
000 = Do not enable
001 = Enable in Timeslot 1
010 = Enable in Timeslot 2
011 = Enable in Timeslot 3
100 = Enable in Timeslot 4
101 = Enable in Timeslot 5
