 ; Function:  LH7A400_cpu_init
 ; 
 ; Purpose: 
 ;	To init the LH7A400 cpu.
 ; 
 ; Processing: 
 ;  	This method brings up core to a ready state. 
 ; 
 ; Parameters: None
 ; 
 ; Outputs: None. 
 ; 
 ; Returns: Nothing
 ; 
 ; Notes: 
 ;    SW7 must be in position 1 for this sequence to work. When SW7 is
 ;    in position 1, FLASH memory is located at base address 0x00000000.
 ;    If there are problems re-programming FLASH (after it has been
 ;    corrupted), try the following sequence:
 ;    * Set SW7 to position 3
 ;    * remove jumper JP36 (wakeup)
 ;    * Power up the EVB and start the Trace32 software
 ;    * Select 'attach' from the CPU System settings panel
 ;    * Press wakeup immediately after you click attack
 ;    * Run the flash programming sequence as normal, but use address
 ;      0x10000000 instead of address 0x00000000 as the FLASH base
 ;      address.
