RS232: Auto Baud Rate feature doesn't support trimmed RCOSC variation

Revision(s) Affected

IWRL1432 ES1.1, ES2.0

Details

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 ES1.1, ES2.0
