Re: Questions on the UART Interface

2004-11-19 by lp2000c

It seems to me that given the problem with the UART interrupt 
register, it is more likely than not that the same problem exists 
with other registers.  Rather than "one race condition is an 
oversight," I would assume similar circuit design would be used in 
all parts of the chip.

In any event, this is something which should be very easy for 
Philips' circuit designers to answer.

As engineers, we can all appreciate that bugs sometimes get through.  
It's the lack of information, once the bug is discovered, that's 
frustrating.
