On page 522 of the LPC15 manual, it says:
"Voltage Ladder can be separately powered down for applications only requiring the comparator function"
I can't find any further details on how to do this. Could you please clarify.
Hi Ian,
It seems you are not using the newest LPC15xx user manual, please download it from this link:
https://www.nxp.com/docs/en/user-guide/UM10736.pdf
About "voltage Ladder can be separately powered down for applications only requiring the comparator function", I think it is register CMPn[VLADEN], you can find each comparator has this bit to control the voltage Ladder, I think when it is disabled, the according voltage Ladder is powered down.
Wish it helps you!
Have a great day,
Kerry
