2.2.3 I/O Space
The I/O map for the TMS320F240 EVM is shown below:
2.3 Onboard UART
The TMS320F240 EVM has a TL16C550 UART mapped into the I/O space of the F240
at locations 0x0010 - 0x0018. The UART allows users to use this resource for data
logging, code debugging or other application features. Appendix C contains the
programming information for the TL16C550 device.
2.4 Oscillator Selection
The TMS320F240 EVM is equipped with a 10 Megahertz oscillator. When the
processor resets the PLL Clock Module defaults to CLKIN/2 yielding a 5 Mhz clkout.
The user should refer to the "PLL Clock Module" section in the TMS320F240 User's
guide for valid clock configurations.
