LMX2572LPEVM: I have a question about the value of register R112

Part Number: LMX2572LPEVM

Hello.

In the datasheet, the maximum value of R112 is 0x01FF.
When read back, it is 0xAA81.
When I measure it with an oscilloscope, it looks like 0xAA81.
Is this behavior correct?

Hi Takeshi-san,

R112 is a read only register, bit 9 - bit 15 represent some other read back register values, they are used for internal debug purpose. It is normal that you may read back some value other than 0.
