Uponreset, bit D15 is set to 0, bit D14 is set to 1 and the remaining bits are don’t−care. These registers are read only.If buffer mode is enabled, then the results of all ADC conversions are placed in the buffer data register. Thedata format of the result word (R) of these registers is right-justified which is as follows:D15MSBD14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0LSBFUF EMF X ID R11MSBBITNAMERESETVALUEREAD/WRITER10 R9 R8 R7 R6 R5 R4 R3 R2 R1 R0LSBFUNCTIOND15 FUF 0 R Buffer Full FlagThis flag indicates that all the 64 locations of the buffer are having unread data.D14 EMF 1 R Buffer Empty FlagThis flag indicates that there is no unread data available in FIFO.
