During reset, the TRIM value is initialized to a factory pre-programmed value to adjust the oscillator frequency to 7.373 MHz, +-1 %. (Note: the initial value is better than 1 %; please refer to the P89LPC932A1 data sheet for behavior over temperature).

fRCOSC internal RC oscillator frequency Min 7.189 Max 7.557 MHz

My calculator says, this is +-2.5%.
Does Philips use some different calculator? :-)
