LCALL SETY
MOV EEEE,#0X06
LCALL SETPAGE
LCALL H8X16
AJMP $
H8X16:
MOV R0,#0X10
MOV DPTR,#HZOO
CLR AAA ;AAA=0=上半字
H2:MOV R1,#0X08 ;写上8个Y列
H3:
MOV A,#0X00
MOVC A,@A+DPTR
LCALL LCDWRDATA ; 调用写数据程序
INC DPTR
INC FFFF ;列地址加一
DEC R0
DJNZ R1,H3 ;判断是否写完8列
JB AAA,H4 ;AAA=0往下，=1跳至HZ2
CLR C ;进位清0为减法做准备
MOV A,FFFF
SUBB A,#0X08
MOV FFFF,A
LCALL SETY ;Y列减8, 即返回扫描
INC EEEE ;页地址加1,即换第2页扫描
