Divides the dc-dc converter clock when the system clock is selected as the clock
source for dc-dc converter. These bits are ignored when the dc-dc converter is
clocked from its local oscillator.
00: The dc-dc converter clock is system clock divided by 1.
01: The dc-dc converter clock is system clock divided by 2.
10: The dc-dc converter clock is system clock divided by 4.
11: The dc-dc converter clock is system clock divided by 8.
Inverts the ADC0 SAR clock derived from the dc-dc converter clock when the SYNC
bit (DC0CN.3) is enabled. This bit is ignored when the SYNC bit is set to zero.
0: ADC0 SAR clock is inverted.
1: ADC0 SAR clock is not inverted.
DC
Inverts the system clock used as the input to the dc-dc clock divider.
0: The dc-dc converter clock is not inverted.
1: The dc-dc converter clock is inverted.
Peak Current Limit Threshold.
Sets the threshold for the maximum allowed peak inductor current. See Table 16.1
for peak inductor current levels.
0: Peak inductor current is set at a lower level.
1: Peak inductor current is set at a higher level.
VDD
Specifies the power source for VDD/DC+ in Sleep Mode when the dc-dc converter is
enabled.
0: VDD-DC+ connected to VBAT in Sleep Mode.
1: VDD-DC+ is floating in Sleep Mode.
DC
Specifies the dc-dc converter clock source.
0: The dc-dc converter is clocked from its local oscillator.
1: The dc-dc converter is clocked from the system clock.
