If this bit is set when bootstrap data is loaded from
DBE (in development mode), then the DBE contents
will be programmed in the OTP.
This field is checked when an ‘ON’ transition is
requested. A non-zero value is used to confirm valid
data.
If OTP_CUST_FINAL is set in the OTP and also set in
the DORW, then no further Writes are possible to the
OTP.
DC-DC1 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
DC-DC1 Switching Frequency
00 = Reserved
01 = 2.0MHz
10 = Reserved
11 = 4.0MHz
DC-DC1 Clock Phase Control
0 = Normal
1 = Inverted
DC-DC1 ON Voltage select
DC1_ON_VSEL[6:0] selects the DC-DC1 output
voltage from 0.6V to 1.8V in 12.5mV steps.
DC1_ON_VSEL[6:2] controls the voltage in 50mV
steps.
DC1_ON_VSEL[6:0] is coded as follows:
00h to 08h = 0.6V
09h = 0.6125V
…
48h = 1.4V (see note)
…
67h = 1.7875V
68h to 7Fh = 1.8V
Note - Maximum output voltage selection in 4MHz
switching mode is 48h (1.4V).
DC-DC1 Output Capacitor
00 = 4.7uF to 20uF
01 = Reserved
10 = 22uF to 47uF
11 = Reserved
