;LCD部分用到的RAM0200H~~~~021FH用到的Rn有R15/R14
;LCD复位子程序(LCD_REST)不需要设事前置直接调用即可
;半屏显现子程序(LCD)在调用前有必要送入页地址 例如:MOV.B #0B8H,LCD_PAGE_BRAM
;CALL#LCD显现上屏
;:MOV.B #0BAH,LCD_PAGE_BRAM
;CALL#LCD显现下屏
;LCDUP_WORD0_BRAM~~~LCDUP_WORD6_RAM是上屏显现字的代码寄存器一屏显现7个字
;LCDDOWN_WORD0_BRAM~~~LCDDOWN_WORD6_RAM是下屏显现字的代码寄存器一屏显现7个字
;每屏显现是以中心为基准向两头均匀显现在调用半屏显现子程序时现已主动核算LCD的列地址
;清屏指令可分全屏铲除(LCD_CLEAR_ALL)和半屏铲除(LCD_CLEAR)
;注 全屏铲除子程序不需进口直接调用就行而半屏铲除子程序在调用前进口与半屏显现子程序相同
