Reference manual sections 1-26 apply to all dsPIC30F devices unless specific supplemental sections are called out.

Part II dsPIC30F1010, dsPIC30F2020, and dsPIC30F2023 devices only

Reference manual sections 27 through 34 are supplemental/additional to sections 1 through 26. For example, section 31 details a 10-bit ADC 2MSPS module operation and applies to a specific subset of dsPIC30F devices. Section 17 and 18 details ADC module operation, however, they apply to another subset of dsPIC30F devices.
