FLD自动显示引脚
当FLDC模式寄存器的自动显示控制位
(地址0EF4
16
)被设置为“1”, P0,P1, P2,P3和P8的端口
作为荧光检测器自动显示标签。
当使用FLD自动显示模式,设置每个端口的
FLD销或使用相应的开关稳压的通用端口

该设置可以通过写一个值到FLD /端口的交换机进行
寄存器(地址0EF9
16
到0EFB
16
)每个端口。
该设置可以在比特为单位来执行。当“ 0”被设置,该端口
被设置为通用端口。当“ 1”被设置,该端口被设置为
在FLD引脚。对所用的荧光检测器引脚是没有限制
作为段引脚或数字引脚。
设置方法
在FLD /交换机端口寄存器的各个位(地址0EF9
16
–0EFB
16
)可以设置每个销
任一端口的FLD ( “1”)或通用端口( “0”) 。

在FLD /交换机端口寄存器的各个位(地址0EFB
16
)可以设置每个引脚要么
荧光检测器端口( “1”)或通用端口( “0”) 。
输出可以通过端口P8 FLD输出控制寄存器被逆转(地址0EFC
16
).
端口输出格式CMOS输出格式。当使用端口作为显示销,驱动器
必须从外部安装。
