#103446 - OK, nevermind. The whole code is way too
Responding to: ???'s previous message
big to post. The comments in the ASM are those generated by SDCC. It is exactly as SDCC generates it. I did cut-n-paste the section of ASM that deals with the FOR loop.

My only question about the 80c552 was whether or not an ADC conversion puts the rest of the program execution on hold. The Philips documentation doesn't say. Their example program seems to hint that the conversion is done in parallel. I assure you, the code compiles, runs, and sends back a report of voltages measured over a short interval. It's just the timestamps were 120 cycles apart which I thought was disappointing. Counting cycles in the FOR loop ASM code added up to 70.
