TCH tap: extend DL sniffing feature to support CSD modes Our debug feature for TCH DL sniffing reads the content of the DSP's a_dd_0 buffer (or a_dd_1 for TCH/H subchannel 1) at appropriate times and forwards captured bits to the host. This feature was originally implemented for TCH/FS, TCH/EFS and TCH/HS - now extend it to cover TCH/F data modes too.

|  Description  :  This function checks if the element is to be patched

|
|  Parameters   :  globs - entity/code information (containing nesting stack)

|
|  Return       :  FALSE if real coding function is to be called, TRUE otherwise
|                  if validflag is set, TRUE means, the element is identified
|                  in the patch list
