 TRM_Mini51DE_Series_EN_Rev1.03   ,
 在PHCHG 的寄存器说明中, 如下关于10 和11的说明是错误的,明显就没有P3.3这个引脚。
 
 CMP1SEL
 Select the positive input source of ACMP1.
 00 = Select P3.1 as the input of ACMP1.
 01 = Select P3.2 as the input of ACMP1.
 10 = Select P3.3 as the input of ACMP1.
 11 = Select P3.4 as the input of ACMP1.
