LVR[7] 
LVR[6] 
    LVR[7] : if LVR[7] write ‘1’, low voltage reset function enable. 
            default is ‘0’, low voltage reset function disable. 
    LVR[6] : if LVR[6] write ‘1’= 2.1V reset. if LVR[6] write ‘0’= 2.8V reset. 
            default is ‘0’= 2.8V reset. 
** Port I/O high driving set 
   if write ‘0’ = set I/O to high driving current mode. 
   if write ‘1’ = set I/O to normal driving current mode. 
   default is set ‘1’.
