3. Driver for the open function has changed from previous SDK releases The initialization of the SCI Driver is now done statically intead of dynamically If using both the Codec and SCI drivers open the Codec driver first followed by the SCI driver This is due to the SCI pins being multiplexed with the pins used to configure the Codec Also note that once the SCI device is opened the Codec cannot be re configured The COP Driver and COP Application have been included but have not been tested since they require a stand alone mode of operation for the DSP CodeWarrior Debugger not attached The RED_LED has been removed from the SDK due to a conflict with a chip select to external memory The RED_LED is still on the EVM however it is not accessed by the SDK The v 22bis test project does not work The g 726 demo is noisy when the target is External RAM The vrlite 1 CPT Caller ID V 8bis and V 22bis demos do not work due to insufficient audio levels on the 56852 EVM These demos have been included though so the user will have an example of how to use them The VAD G 165 and G 168 Demos sometimes fail due to the PC not being able to keep up with the DSP when the DSP is writing data to the PC via the serial port There is not any flow control for these applications thus the PC cannot tell the DSP to stop transmitting These tests are more successful when using a faster PC gt 700MHz If projects are changed to use optimization level 4 some te

5. DSP This version will also work with the older revisions of the DSP The TDC1 Driver for the DSP56852 and DSP56858 was modified to correct a timing problem due to the new revision date stamp 0233 or 0234 of the DSP This version will also work with the older revisions of the DSP The DTMF Generation Library document was updated to better describe the return values The PCS Driver was enhanced by adding an option to configure the DRV bit in the BCR register The File I O application was enhanced by allowing the user to change the COM port and by having it display the filename when an error is detected The QuadTimer Driver was enhanced by having it check for NULL Callback functions and by fixing bugs when configured for gtOneShot qtPulseOutput qtFixedFreqP WM and qtVariableFregPWM modes The RFFT and RIFFT functions in the DSP Function Library were enhanced by fixing a scaling bug The RFFT RIFFT CFFT and CIFFT functions in the DSP Function Library were enhanced by fixing a potential misalignment bug The PC Master Software Driver was enhanced by adding the Recorder functionality The SPI Driver was enhanced by fixing a compile error when using the SPI_LTRANSMISSION_DATA_SIZE SPI MODE_MASTER or SPI_MODE_SLAVE commands The Timer Services were enhanced to give a more accurate timer The old timer could have been off by as much as three percent The Serial Flash Programmer had to change due to CodeWarrior 2 0 changing the format
