16.12. DC-DC Converter Register Descriptions
The SFRs used to configure the dc-dc converter are described in the following register descriptions. The
reset values for these registers can be used as-is in most systems; therefore, no software intervention or
initialization is required.

MINPW
R/W
Specifies the minimum pulse width.
00: No minimum duty cycle.
01: Minimum pulse width is 20 ns.
10: Minimum pulse width is 40 ns.
11: Minimum pulse width is 80 ns.
DC-DC Converter Switch Select.
Selects one of two possible converter switch sizes to maximize efficiency.
0: The large switches are selected (best efficiency for high output currents).
1: The small switches are selected (best efficiency for low output currents).
Reserved. Always Write to 0.
ADC0 Synchronization Enable.
When synchronization is enabled, the ADC0SC[4:0] bits in the ADC0CF register
must be set to 00000b.
0: The ADC is not synchronized to the dc-dc converter.
1: The ADC is synchronized to the dc-dc converter. ADC0 tracking is performed
during the longest quiet time of the dc-dc converter switching cycle and ADC0 SAR
clock is also synchronized to the dc-dc converter switching cycle.
DC
Specifies the target output voltage.
000: Target output voltage is 1.8 V.
001: Target output voltage is 1.9 V.
010: Target output voltage is 2.0 V.
011: Target output voltage is 2.1 V.
100: Target output voltage is 2.4 V.
101: Target output voltage is 2.7 V.
110: Target output voltage is 3.0 V.
111: Target output voltage is 3.3 V.
