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
Figure
15.
In the BUCK_SEL field choose VBUCK_A (see the red arrow in
Figure
15), 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.
