I want to use the 87C576 with EPROM external memory. Can I use the PWM0 and PWM1 pulse width modulators at the same time that I am accessing external memory?

No. You cannot employ PWM0 or PWM1 while accessing external memory because the Port 2 pins will already be occupied with external memory operation. This makes it impossible for the PWM0 and PWM1 pulse width modulators to work at the same time as the external memory.
