In AD7091R-5 datasheet Rev. A, POWER-DOWN MODE chapter (page 32), it says:
"To enter power-down, write to the power-down configuration bits in the configuration register, as seen in Table 15. To enter full power-down mode, set the sleep mode/bias generator bit to 1, and set the internal reference bit to 0".
This means setting CONFIGURATION[P_DOWN]=0b10.
However, further, it says:
"To exit this mode of operation and power up the AD7091R-5, set the MSB of the P_DOWN word to 1."
i.e. CONFIGURATION[P_DOWN]=0b1x. This is contradictory. We were expecting "set the MSB of the P_DOWN word to 0."
Is this a documentation error? If so, can it be corrected please?
