I am attempting to use the ADC in dual single ended mode (user manual section 39.6.16, ADC command low buffer registers, CTYPE == 0x03) on the LPC55s69 but so far I have not been successful. Other chips in the family (LPC553x) appear to have a very similar ADC and have a few added bits/fields in the same register that seem to pertain to this mode. But the corresponding bits/fields in the LPC55s69's user manual are reserved.
Has anyone else had any success using the ADC in dual single ended mode? Is this feature not supported in the LPC55s69?
