HSADC Question with KV56

[derekcook]

I am a little confused by the KV58 dual parallel conversion example. I see in the example they are using PTE1 and PTE2 which is HSADC0B_CH17 and HSADC0B_CH10. 

Then they go to assign these channel numbers

How is ADCB_CH7, ADCB_CH6, ADCA_CH2, ADCA_CH6 linked to HSADC0B_CH17 and HSADC0B_CH10? 

I am wanting to use both HSADC0 and HSADC1 to do 2 parallel conversions of the below pins on the KV56. I'm also wanting to use PDB to trigger the conversion which I don't see an example for. 

A	HSADC1A_CH2
B	HSADC1B _CH2
C	HSADC0B _CH2
DC	HSADC0A _CH14

However, I don't quite understand the ADCA and ADCB channel assignments. I assume I don't just pick a channel 0-6 on ADCA and then 7-15 for ADCB or do I? I would think somehow the channels are linked to HSADC0A _CH14 for instance.

One question I do have - for the below to use CH 14 (pin 83) would this be mux number 4?

CH 40.1.2 has a table to show how each pin connects to the HSADC. Looks like my options are below: 

Pin	Name	Pin selection	HSADC connection
18	A	HSADC1A_CH2 / HSADC0A_CH2	HSADC0A_CH2 / HSADC1A_CH2
20	B	HSADC1B _CH2 / HSADC0A_CH10	HSADC0A_CH6 mux ch10 / HSADC1B_CH2
PTB0	C	HSADC0B _CH2	HSADC0B_CH2
PTB2	DC	HSADC0A _CH14	HSADC0A_CH6 mux ch 14
