Hi, I am using the DSP56858. I am having some problems understanding how the HI8 works. Is there a way that I can send a block of data to the output of the DSP without having the host processor connected? Is the host processory required to be connected and produce signals to trigger the DSP to send? Is there a way I can produce these signals

Hi, I have a couple of questions related to interfacing the SPI module (DSP56858) to a temperature sensor (TMP122: http://focus.ti.com/lit/ds/symlink/tmp122.pdf ). The TMP122 has a single I/O line whereas the DSP uses two separate lines, MOSI and MISO. Please tell me if this is feasible to use with the DSP: Tying MOSI and MISO together and tri-stating MOSI each time I wanted to r...


Prescaler vs. Counter output pin as the primary source

Hi, I am using the DSP56858. This question relates to the Quad Timers. What is the difference between a prescaler as a primary source and using a counter ouput pin as a primary source? On Timer3, I am generating a clock pulse which uses a prescaler as the primary source and then toggles the OFLAG output on successful compare.

Stop vs Fast Stop mode

Hi, I am using the DSP56858. I have a question about the two Stop modes available with this DSP. In the manual it mentions that when OMR6_SD is set to zero, the SIM provides an extreme low power Stop mode by shutting down the PLL. When OMR6_SD is set to one, the SIM supports a fast Stop mode recovery and does not affect the state of the PLL when Stop mode is entered. How do I set this...
