Hi,
I use the chip is 16 f877a, crystals is 19.6608 Mhz.
I want to use interrupts produce 500 KHZ square wave signals, but interrupt the maximum frequency of 19200 hz (1:1). How should I do? Help me, thank you

Hello

Use a 20MHz crystal.
PWM is used.
9 = the value of the Period register, duty cycle = 4 or 5
