PRODUCTION DATA
DB12/SDOA is a dual-function digital input/output pin.
In software parallel interface mode (SER/BYTE/PAR = 0, HW_RNGSEL[1:0] = 00), use this pin to program the device during the write operation and read data during the read operation. See the Section 7.5.1 section for further details.
In hardware parallel interface mode (SER/BYTE/PAR = 0, HW_RNGSEL[1:0] ≠ 00), use this pin to read data from the device. See the Section 7.5.1 section for further details.
In byte interface mode (SER/BYTE/PAR = 1, DB9/BYTESEL = 1), tie this pin to DGND.
In serial interface mode (SER/BYTE/PAR = 1, DB9/BYTESEL = 0) this pin acts as the serial data output A. See the Section 7.5.3 section for further details.
