Hi all,
If I connect a serial device to our MCP855T Processor based customized board
, these is performance difference between Internal UART (SCC) and external
UART (16C554A) , the External UART performance is better than the internal
UART .
what could be the problem , How can I make the Internal UART work with
better performance.
Thanks in advance
Regards,
KP

Can you be more specific about what you mean by 'better performance' ?
