TMS320F2812: Question about TMS320F2812PGFA

Part Number: TMS320F2812

Tool/software:

Hello:

At present, the two pins XA [15] and XA [16] of the chip circuit are connected to external RAM on the other end. If there is a short circuit, if the DSP program outputs a high level to pin XA [15] and a low level to pin XA [16], and these two pins are short circuited, what is the actual output high? Is it still low? Thanks!!!

  • Jimmy,

    It will be somewhere in-between the two.   Could be high, low, or ambiguous.  This condition could cause device damage if persistent since the output buffers will fight each other and consume a lot of current.

    Best regards,

    Jason
