Other Parts Discussed in Thread: TMS320F28035
Hi,
I have a question on the I2C communication of the microcontroller Picollo TMS320F28035. If anyone can help me, thank you very much!
The reference guide sprufz9d for the I2C communication of TMS320x2802x, 2803x says that the value of the bit I2CFFEN (bit 14) of the register I2CFFTX is 0 after reset of microcontroller (page 36). However I have found that it is not true.
When I first loaded my program to the microcontroller, I verified that the bit I2CFFEN (bit 14) of the register I2CFFTX is 0 as shown in the reference guide. I reseted the microcontroller by using a switch to start a watchdog. After reset I checked this bit again and found that its value was not 0 any more. It was 1. Moreover, some other bits of the register I2CFFTX are not 0, either. I wonder which mecanism changed the default values of these bits while the reference guide shows that their default values are 0 after reset of the microcontroller.
Thanks a lot for any helpful answer!
