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). P89LPC932A1_1.pdf on page 50 said:
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? :-) Jan Waclawek |
