TSC2101 Buffer Data Registers (Page 3)
The buffer data registers of the TSC2101 hold data results from the SAR ADC conversions in buffer mode. Upon
reset, bit D15 is set to 0, bit D14 is set to 1 and the remaining bits are don’tcare. These registers are read only.
If buffer mode is enabled, then the results of all ADC conversions are placed in the buffer data register. The
data format of the result word (R) of these registers is right-justified which is as follows:

FUNCTION
D15 FUF 0 R Buffer Full Flag
This flag indicates that all the 64 locations of the buffer are having unread data.
D14 EMF 1 R Buffer Empty Flag
This flag indicates that there is no unread data available in FIFO. This is generated while reading the
last converted data.
D13 X R Reserved
