PB internal RTC in F269

When I use Keil simulator for ST10F269, I must programmed the RTCP register with 0x000F FF63 for have a interrupt at 1,0048ms with a claock CPU at 4x10MHz=40Mhz.

I see on simulator that the RTCD register is load with 0x000F FF63 and incremented thrue 0x0000 0000 before generate a interrupt and relaod with 0x000F FF63.

But on F269 this value générate a interrupt at 6,709 secondes, I must programmed the RTCP with 0x0000 006D for have a interrupt at 1,0048ms.

In documentation of F269 it is write that RTCD is incremented, it is conform with simulator.

The other timers by ex. T6 prgrammed with the same clock generate a good interruption.

Any body have a explication for this?

Tanks.
