DAC3174: IO Test pattern

Part Number: DAC3174


Hi,

when I'm running IO test pattern, I should see the result at register 0x04.

at the datasheet the explanation is:

"The values of these bits tell which bit in the input word failed during the io-test pattern comparison. [13:7] match up with the 7 bits from port A and [6:0] match up with bits from port B."

how does it sorted?

is it the 7bit MSB of each port?

or the 7bit LSB of each port?

or is it the 7bit MSB of port A and the 7bit LSB of port B?

or is it the 7bit LSB of port A and the 7bit MSB of port B?

Best Regards,

Ran
