#define HD66781S_SEND_COMMAND(c)    {*(volatile uint16 *)0x58000000 = c;}
#define  HD66781S_SEND_DATA(d)    {*(volatile uint16 *)0x58008000 = d;}
展讯平台是通过多媒体芯片和LCD相连的（VC0529）上面的0x58000000，0x58008000
是展讯芯片的寄存器的值吗？*(volatile uint16 *)0x8A000000&=~b_10
？*(volatile uint16 *)0x8A000000&=|b_10这个0x8A000000又是那个值。
