10. //    This program requires the DSP2833x header files.
11. //
12. //    This program requires an external I2C EEPROM connected to
13. //    the I2C bus at address 0x50.
14. //
15. //    As supplied, this project is configured for "boot to SARAM"
16. //    operation.  The 2833x Boot Mode table is shown below.

44. // DESCRIPTION:
45. //
46. //    This program will write 1-14 words to EEPROM and read them back.
47. //    The data written and the EEPROM address written to are contained
48. //    in the message structure, I2cMsgOut1. The data read back will be
49. //    contained in the message structure I2cMsgIn1.
50. //
51. //    This program will work with the on-board I2C EEPROM supplied on
52. //    the F2833x eZdsp.
