The default value for the 0x1A48 register on page 131 of the datasheet for AD9689 is 0x14, but the default value I actually read out is 0x54.
Firstly, in my program, the 0x1A48 register was not configured.
To further verify, after resetting ad9689 (writing 0x81 to the 0x0000 register), the value read from the 0x1A48 register remained at 0x54.
Is the datasheet written incorrectly?
