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
conversion sequence diagram.
