Not that I recall, but he has published recently, so it should be possible to contact him:

I had no problem with the original link.

The TI trick to get 180ps PWM resolution on some of their MCUs is interesti ng.

very MCU. Then you could design the hardware you need rather than trying t o fit the design into the limited hardware available.

Is there a way to "+1" this reply? :) I just finished a product that required a 24-hour timer under certain condi tions, while it was doing its other normal functions. No big deal I guess; a timer interrupt and some registers, with some care and attention to not spending too much time in the interrupt service routine.

But at 8-bits? 24 hours is a lot of counting! :)

We just built an 8-hour timer into an FPGA to ignore triggers after one working day, and so prevent the customer from using our code (un-paid-for demo code) in a real production machine. People wouldn't like their 24/7 fab lines to shut down every 8 hours.
