g4eml 957d0d8d34 Change ADC1 to reduce number of interrupts. 
Disable interrupts for ADC1. 
Every time ADC0 interrupts (24Khz) read the current conversion from ADC1 and software trigger a new one. 
This way there will always be an ADC1 conversion available whenever ADC0 interrupts.

g4eml cb30a8d357 Adjust ADC pre-trigger setting for external TCXO 
External TCXO was not working with Pre-Trigger set to B.
This change sets it to A which appears to work.
