Can a touch bank consist of all channels?

Can a touch ''bank'' of the STM32 touch library consist of 9 channels so they will be acquired simultaneously? (I use stm32l053). 

My issue is that I have 9 touchkeys and want to acquire the touchkeys as fast as possible. Is it needed to declare 9 banks? I would like to distinguish the touchkeys individually.

I've read http://www.st.com/st-web-ui/static/active/en/resource/technical/document/user_manual/DM00075710.pdf but cannot find any relevant information on this topic.

Hi adoxp,

Please note that STM32L0 isn't supported in UM1606.

However, I suggest you have a look to other application notes related to touch sensing. You may find there some helpful information:
