7.5.1.5 Streaming Mode
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. The ADDR_ASC bit (register 000h, bits 5 and 2) controls whether the address value ascends (increments) or descends (decrements). Streaming mode can be disabled by setting the ADDR_HOLD bit (see the user SPI configuration register). Figure 87 shows the streaming mode transaction details.
Figure 87. Serial Interface Protocol: Streaming Read/Write See the Register Maps section for detailed information regarding the registers.
NOTE
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 time.
