/*
P1	0  0  B  1  	W/S  M2  M1  M0
B：调整负向显示字符时的屏面边界，
		通常B=1
   		B=0：画面首行为边界；B=1：无边界。
W/S：驱动器系统配置。
	W/S=0	为单屏结构LCD的驱动系统；
	W/S=1	为双屏结构LCD的驱动系统。
M2： 选择外部字符发生器的字符点阵格式；
	M2=0：	8×8点阵字体
	M2=1：	8×16点阵字体
M1： 选择外部发生器CGRAM的字符代码范围：
	M1=0：	选择80H-9FH范围字符代码；
	M1=1：	选择80H-9FH和E0H-FFH两个范围的字符代码。
M0： 内、外字符发生器的选择
	M0=0	为内部字符发生器有效；
	M0=1	为外部字符发生器有效，此时内部字符发生器被屏蔽,字符代码全部供给外部字符发生器使用。

P1=B0011_0100

P2	WF    0    0    0    0   fill  FX fill
WF：选择驱动器的交流驱动器的波形，通常WF=1
FX：显示字符的宽度，FX=字符高+字间距，FX=0-7H

P3	    0    0    0    0   fill   FY  fill fill
FY：显示字符的高度，FY=字符高+行间距，FY=0-FH

P4	fill fill fill  C/R  fill fill fill fill
C/R：	设置有效显示窗口的长度。C/R表示在LCD上有效显示的字符数。
	比如：LCD一行能显示30个字符，C/R设置为30，则一行全显示满了；
	若C/R设置为25，则LCD一行左起显示25个字符而后5个字符位置为空白。C/R取值在00H-EFH。

P5     fill fill fill   TC/R  fill fill fill fill 
TC/R：将晶振频率fosc转换成LCD工作频率的时间常数，TC/R由公式：
         fosc≥TC/R×9×L/F×FR
         TC/R≥C/R+4
	联合求解。一般情况下的简便计算，以C/R+4的值设置即可。其中L/F为扫描点行数，FR为LCD驱动频率，
	通常FR=70Hz
P6	fill fill fill  L/F fill fill fill fill 
L/F：LCD的点行数，取值在00H-FFH范围内。
P7	fill fill fill  APL  fill fill fill fill 
P8	fill fill fill  APH  fill fill fill fill 
AP：	显示屏一行所占显示缓冲区的字节数，AP为双字节参数：APH高8位，APL低8位。通常取：AP=C/R+1
