TMS320F28379D: EMIF

Gp
Intellectual 695 points
Part Number: TMS320F28379D


Hi, 

1. How can EM1Dx pins be configured to accept digital inputs since it is an I/O pin?

2. If  digital pins (D0-D7) of external asynchronous device is connected physically to EM1Dx data pins, then in which location (Location given in the below figure) the data from EM1Dx pin will be stored?

3. How the data get stored in a particular location? Does EM1Ax Address pins usage come into picture to handle this situation?

    Hi, due to inclement weather in our region, many of our subject matter experts are without power and unable to provide support at this time.  An expert will get back to you as soon as possible but it likely will not be until next week.

    Hi Ganesh,

     1. How can EM1Dx pins be configured to accept digital inputs since it is an I/O pin?

    As soon as a pin is configured for EMIF function, this pin changes the direction as input or output as per EMIF operation (read vs write). User need not to worry about this.

     2. If  digital pins (D0-D7) of external asynchronous device is connected physically to EM1Dx data pins, then in which location (Location given in the below figure) the data from EM1Dx pin will be stored?

    That is correct. For write it'll store the data at these location and for read, it'll read from these location.

     3. How the data get stored in a particular location? Does EM1Ax Address pins usage come into picture to handle this situation?

    This is correct.
