Include            : incap.h
 
Description        : This function reads all the pending Input Capture buffers.
 
Arguments          : buffer - This is the pointer to the locations where the 
                     data read from the Input Capture buffers have to be stored.
 
Return Value       : None
 
Remarks            : This function reads all the pending Input Capture buffers
                     until the buffers are empty indicated by the ICxCONx<ICBNE>
                     bit getting cleared.
