RESET
R/W
0b
Reset device
0b = No effect
1b = Resets all registers to the default values
Reading this bit always returns 0.
6
SSCEN
R/W
0b
Spread spectrum clocking enable
0b = SSC operation disabled
1b = SSC operation enabled
5
SWEN
R/W
1b
Software enable
0b = Switching disabled (register values retained)
1b = Switching enabled (without the enable delay)
4
FPWMEN
R/W
0b
Forced PWM enable
0b = Power-save operation enabled
1b = Forced-PWM operation enabled
This bit is logically ORed with the MODE/SYNC pin. If a high level
or a synchronization clock is applied to the MODE/SYNC pin, the
device operates in forced-PWM, regardless of the state of this bit.

0b = Output discharge disabled
1b = Output discharge enabled

HICCUPEN
R/W
0b
Hiccup operation enable
0b = Hiccup operation disabled
1b = Hiccup operation enabled. Do not enable hiccup operation
during stacked operation.

VRAMP
R/W
10b
Output voltage ramp speed when changing from one output voltage
setting to another
00b = 10mV/µs
01b = 5mV/µs
10b = 1.25mV/µs
11b = 0.5mV/µs
