3.10 A/D Converter Result Registers
These read-only registers hold an 8-bit conversion result. Writes to these registers have no effect. Data
in the A/D converter result registers is valid when the CCF flag in the ADCTL register is set, indicating a
conversion sequence is complete. If conversion results are needed sooner, refer to
shows the A/D conversion sequence diagram.
