Hi ktwei,
You're correct. The amount of time it takes for DJNZ R1, DELAY is 292 microseconds.
It was my mistake. If the 8051 microcontroller is driven by 11,0592 Mhz XTAL, the 1 microsecond is the amount of time spent during one machine cycle, 12 oscillator period (and not one oscillator...
Hi Tamasco
Even if ADC is running continuously you still need an initializing pulse following power-up. The WR and INTR node should be momentarily forced to logic low following a power-up cycle to guarantee operation.

IanP, my apologizes.
I didn't noticed the FB at the end, even if for me it's obvious now (it needs 16K buffer not only 4K).
Going deeper I found that without a programmer able to provide Quick Pulse Algorithm, even the Noel Rios's schematics is useless (even tying the P24 toward A12 and P25...
Ivan,
I understand you're astonished of ENC28J60's features, but your post comes a little bit too late for asahin11 and out of topic. He requests "This circuit will connect to a site through telephone line ". How can ENC28J60 do this job ?
If you want to deal with PPP you can try at...

Hi zedman,
It's not a common practice to rely on input configuration of a TTL input. Yes it's true that leaving the input not connected is treated as "1" logic at his input.
But noise will be always present in the system, more or less, and if RA4 is in...

Yes, this is the main reason for which I said that dissasembling CY fw it's useless as long as we have the OS and BL bin file provided by Microchip. To start coding from scratch for 4550 and simulate the CY fw would be time consuming and worthless.
That's I appreciate...
