I was wondering if anyone has seen the errata on the UART in terms of the hardware race condition that Robert pointed out many posts ago. Also, I was wondering if the read-the-IIR-once-and-only-once solution is the workaround. The errata states that reading the IIR will only clear the THRE interrupt on UART1, however, the user's manual states otherwise. I'm waiting to hear back from a Philips FAE on this. Thanks, John
