What I mean by "mixed" is whoever wrote that manual has the RAM and ROM values incorrectly displayed the wrong way around.
Another way of saying that is they have the 2 values shown as the opposite of what they should be.
The manual shows the device having 512 MB of RAM.
That is not correct, it only has 64 MB of RAM.
ROM size is sometimes used by manufacturers to describe the size of a device's total internal storage partition, or partitions if there's more than 1.
That manual has the internal storage listed as 64 MB.
That is not correct, in that instance, ROM should be listed as 512 MB
Spoiler: The manual
