Hello ,
the chip is MC9S12ZVML128MKH, CW10. 6.4
In the configuration of the Init_GDU, the “Current sense amplifier” can not be disabled or the “Amplifier
Output” can not be disabled , does this is a bug or it is sure can not disabled ?
I want to use the pin “PAD5_KWAD5_AN1_0_AMP1” as AD channel , while in the
“Init_GDU” can not disable this pin .
Thank you very much !

Hello,
If you look in the reference manual of the derivative, you can find that there is not any routing register for AMP0/1 pins:
The routing is done by enabling the current sense amplifier, i.e. you cannot route this pins as ADC when the current sense amplifier is enabled (it is also higher priority).
For details see the reference manual of the derivative.
