7.4.1.13 DB14/HBEN

DB14/HBEN is a dual-function, digital input, output pin.

When the device operates in parallel interface mode (PAR/SER/BYTE SEL = 0), this pin functions as a digital output. In this mode, this pin outputs the DB14 of the conversion data when both the CS and RD signals are pulled low.

When the device operates in parallel byte interface mode (PAR/SER/BYTE SEL = 1 and DB15/BYTE SEL = 1), this pin functions as a digital control input pin that selects if the MSB byte or the LSB byte is output first. If the DB14/HBEN pin is tied to logic high, then the MSB byte is output first followed by the LSB byte and vice-versa if this pin is tied to logic low.

When the device operates in serial interface mode (PAR/SER = 1), tie this pin to AGND or to a logic low input.
