hi dears
i have designed the board based on MPC565 . and i forgot make pull-up of MODCK signals for set PLL to external Oscillator. and now how can i set it to external Oscillator ?? without pull-up MODCK signals.
is there any way???
Hi,
by default, there's internal weak pull up resistor on all MODCK pins:
If nothing else is connected to these pins, this mode should be selected:
After PORESET is negated the pins can be used as interrupt pins. If the user intends to use these pins as interrupts then it is necessary to ensure that no interrupt signals to these pins are asserted during PORESET. The easiest way to achieve this is to gate any interrupt source to these pins with the /HRESET signal.

yes but i need to have 011 set on MODCK pin
how can i set it?
