PRODUCTION DATA.
Holding the SDI line low continuously (equivalent to writing a 0 to all 16 bits) during device operation continues device operation in the last selected mode (STDBY, PWR_DN, AUTO_RST, or MAN_Ch_n). In this mode, the device follows the same settings that are already configured in the program registers.
If a NO_OP condition occurs when the device is performing any read or write operation in the program register (PROG mode), then the device retains the current settings of the program registers. The device goes back to IDLE mode and waits for a proper command to be entered before executing the program register read or write configuration.
