The Data Registers store the latest data from either the sinc filter or the integrator output for each filter module.
The data is presented in two's complement 16-bit or 32-bit format. The bit DR in the Integrator Parameter
Register controls the bit width of the Data Register. It takes two bytes to read the 16-bit formatted data and four
bytes to read the 32-bit formatted data. The acknowledge flag for the appropriate filter module is cleared when
reading the Data Register. Table 24 describes the Data Register in 16-bit formatting.

31 – 0 D31 – D0 Data from the sinc filter or the integrator filter in 32-bit formatting.
The Time Registers store the latest time information for each filter module. The data is presented in straight
binary 16-bit format. The bit TMx in the Control Parameter Register controls the mode of the time measure unit.
Table 26 describes the Time Registers.
