/*** fnDumpTb4000 - output tb for R4000
*
*   Purpose:
*       Function of "dt<range>" command.
*
*       Output the tb in the specified range as tb values
*       word values up to 1 value per line.  The default
*       display is 16 lines for 16 64-doublewords total.
*
*   Input:
*       startaddr - starting address to begin display
*       count - number of tb entries to be displayed
*
*   Output:
*       None.
*
*   Notes:
*       memory locations not accessible are output as "????????",
*       but no errors are returned.
