AT/PS2 Keybord - PIC Interface?

Hi,

Every PIC18 has got a x4 HSPLL oscillator mode. So you can use an external 10MHz crystal to effectively get 40 MHz Fosc. For internal 8MHz you need to configure osccon to enable HSPLL and get 8 x 4 = 32MHz from the internal oscillator.

Thank you Sougata. I will give this a try and report back. And thank you for teaching me about HSPLL.
