我的程序是这样的，但是我在配置里没有改。他默认的端口配置是high z analog
然后我打开PSCConfigTBL.asm发现里面的代码如下：
LoadConfigTBL_pdproject25_Ordered:

M8C_SetBank0
mov reg[00h], 00h ; Port_0_Data register (PRT0DR)

mov reg[01h], ffh ; Port_0_DriveMode_1 register (PRT0DM1)
M8C_SetBank0
mov reg[03h], ffh ; Port_0_DriveMode_2 register (PRT0DM2)

上面表明模式还是在HIGH Z ANALOG . |
