TMS320DM355ZCE270 Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the DM355?
  The recommended power-on sequence is to apply power to the DVDD and CVDD pins first, followed by the AVDD and DVDDIO pins. This ensures that the internal voltage regulators are powered up correctly.
• How do I configure the clock settings for the DM355?
  The clock settings for the DM355 can be configured using the Clock Enable Register (CKEN) and the Clock Configuration Register (CKCFG). The CKEN register enables or disables the clock for each module, while the CKCFG register configures the clock source and divider for each module.
• What is the maximum operating frequency of the DM355?
  The maximum operating frequency of the DM355 is 270 MHz. However, the actual operating frequency may be lower depending on the specific application and the clock configuration.
• How do I use the EMIF (External Memory Interface) on the DM355?
  The EMIF on the DM355 is used to interface with external memory devices such as SDRAM, NOR flash, and NAND flash. The EMIF is configured using the EMIF Configuration Register (EMCFG) and the EMIF Timing Register (EMTIM). The EMCFG register configures the EMIF mode, while the EMTIM register configures the EMIF timing parameters.
• What is the purpose of the Reset Pin (RST) on the DM355?
  The Reset Pin (RST) on the DM355 is an active-low input that resets the device when asserted low. The RST pin can be used to reset the device in case of a system failure or to initialize the device during power-up.
