I want to use LPC54605J256BD100 microcontroller in an applicaion where a pulseon an external pin will trigger an ADC and ADC should sample 12 channels on that single pulse input and give output at the end of the sampling of all the 12 channels.
I was going through the user manual of LPC546xx but couldn't find appropriate description for the required functionality. I have follwoing queries regarding Sequencing feature of ADC in LPC546xx:
1) In busrt mode,
a) Conversion will start after trigger only right?
b) After one sequence(i.e 12 channels sampled), does it stop sampling or initiates a new conversion sequence without any trigger?
2) What is the use of start bit in SEQA_CTRL register?
3) How to acheive the required functionality for my application?
4) Any example code would be helpful
Thanks in advance,
