AC60 Flash size - is the datasheet wrong?

I'm beginning to work with the S08AC60 and I found out that the datasheet (latest version: Rev. 3  8/2011) is conflicting about its Flash size.

At section 4.4.1, the datasheet says:

      MC9S08AC60 — 61268 bytes (120 pages of 512 bytes each)

But looking at figure 4.1 (at the beginning of section 4.1) and calculating the Flash size based on the memory map, I came out with 63.280 bytes and 124 pages.

I also haven't found any errata about this on the MCU documentation.


Just as a comparison, I looked for the datasheet of a similar MCU (S08AW60) and it seems to be right, showing the Flash size as 63.280 bytes and 124 pages.


Can I assume that the S08AC60 datasheet is wrong and its Flash size is 63.280 bytes?
