Dear all,

We have four questions about the DUART Errata (A-004737) in the ‘P2020CE Rev. CC, 01/2016’ document (see the attachment), and we used P2010 CPU.

 

1. what the ‘Previously DUART 1‘ means?

     only the UART1 has this problem and UART2 will be OK?

 

2. besides the software, Does the hardware can generate the ‘break signal’ also? If yes, What's the scenario?

 

3. In the Workaround section: ‘This workaround requires that the break signal be at least 2 character-lengths in duration’. 
How we can know the break signal will durative 2 character-lengths?

 

Thanks a lot.
