There is an easy way to modify the output voltage of BUCKA. This is by using the VBUCKA_CTRL_A
and VBUCKA_CTRL_B registers, see the red box in
In the
BUCK_SEL
field choose
VBUCK_A
(see the red arrow in
), now changing the value
in
VBUCKA_CTRL_A
changes the output voltage. This initiates a DVC transition towards the new
selected voltage.
Figure 15: Output Voltage Control
By toggling the value on
BUCK_SEL
it is also possible to change the output voltage between the
value contained in
VBUCKA_CTRL_A
and the value contained in
VBUCKA_CTRL_B
.
