    MOVC A,@A+DPTR  using this in assembler produces opcode 93 but A value for offset appears in accumulator rather than the value pointed by the DPTR. I am using it to address eeprom at

    RaPe_567536

      I am writing directly in assembler to get speed. Using MOVC A,@A+DPTR produces opcode 93 but the prior A  value (required for the offset) appears in the accumulator afterwards rather than the contents of the eeprom addressed by the DPTR at #8000H. Normal MOVX @DPTR,A works and using INC DPTR works too. Any ideas??
