ATD problem in S12XDP512

Hello,

 

Currently I'm using a start kit from softec to implement a base environment for motor control, but I encountered some problem when I deal with ATD module. follow is my initial code for ATD module:

 

ATD1CTL3 = 0x38;
ATD1CTL4 = 0x80;
ATD1CTL0 = 0x05;
ATD1CTL2 = 0x80;
ATD1CTL5 = 0x32;

 

but in this code, I can't get any data from AD0~AD7, I can only get data from AD8~AD15.

the relation is as follow:

 

data--->PAD08--->ATD1DR0

data--->PAD09--->ATD1DR1

 

but data--->PAD00---> can't found in any register....

 

So it's really bother me a lot. Could somebody also have encountered this problem before? could you give me some hint about this? Thanks a lot in advance.

 

Fatty
