RS232: Auto Baud Rate feature doesn't support trimmed RCOSC variation
IWRL6432AOPES2.0
Once RCOSC is trimmed, the expected clock frequency and the variation observed in frequency (tolerance on RC clock) do not support the required Auto Baud rate setting for RS232.
Currently Auto Baud is disabled by default for ES2.0
