 Name:        »ClearPageMode« - Clear PMMU mode for a memory block.

 Number:      2

 Declaration: ULONG ClearPageMode ( ULONG mode, ULONG start_address, 
              ULONG length );

 Description: The call ClearPagemode clears the PMMU mode for a given 
              block of memory. The following apply:

               Parameter      Meaning

               mode           Bit-vector as in SetPageMode
               start_address  Start address of memory segment
               length         Length of desired segment

              Note: All other bits are reserved for future purposes. A 
              program may only clear those bits that it has set itself 
              previously.

 Return value: The function returns zero on error-free execution. 
              Otherwise a value is returned in which the bits that 
              could not be manipulated are set.
