PRODUCTION DATA
The serial interface supports streaming reads and writes. In this mode, the initial 24 bits of the transaction specifics the access type, register address, and data value as normal. Additional clock cycles of write or read data are immediately transferred, as long as the SCS input is maintained in the asserted (logic low) state. The register address auto increments (default) or decrements for each subsequent 8-bit transfer of the streaming transaction. ASCEND controls whether the address value ascends (increments) or descends (decrements). Streaming mode can be disabled by setting the ADDR_HOLD bit. Figure 6-19 shows the streaming mode transaction details.
See the SPI_Register_Map Registers section for detailed information regarding the registers
The serial interface must not be accessed during ADC calibration. Accessing the serial interface during this time impairs the performance of the device until the device is calibrated correctly. Writing or reading the serial registers also reduces dynamic ADC performance for the duration of the register access times.
