PRODUCTION DATA
To reduce production board costs and application development time, all F28002x devices contain two independent internal oscillators, referred to as INTOSC1 and INTOSC2. By default, INTOSC2 is set as the source for the system reference clock (OSCCLK) and INTOSC1 is set as the backup clock source.
Applications requiring tighter clock tolerance can use the SCI baud tuning example available in C2000Ware (C2000Ware_3_03_00_00\driverlib\f28002x\examples\sci\baud_tune_via_uart) to enable baud matching better than 1% accuracy.
Section 6.11.3.5.1 provides the electrical characteristics of the internal oscillators.
