Difference in time count between R6532 and G65SC32

There is a subtle difference between the NMOS 6532 and the CMOS G65SC32 datasheet regarding the timer of 1 in elapsed time.

It is in the paragraph starting at ‘Once the time has counted down to 00000000, an interrupt will occur ….’
On the 6532 that takes 27T (T is the clock tick), on the G65SC32 28T.
That makes in the example the total elapsed time 443T on the 6532 and 444T on the G65SC32.

Look at these pages about the timer from the datasheets of the R6532 and 6G5SC32 (see below and here)
