MC9S12DT128B Device User Guide — V01.09
– Port M[7:6]
PM7:6 must be configured as outputs or their pull resistors must be enabled to avoid floating
inputs.
– Port P6
PP6 must be configured as output or its pull resistor must be enabled to avoid a floating input.
– Port S[7:4]
PS7:4 must be configured as outputs or their pull resistors must be enabled to avoid floating
inputs.
– PAD[15:8] (ATD1 channels)
Out of reset the ATD1 is disabled preventing current flows in the pins. Do not modify the ATD1
registers!
Document References
The Device User Guide provides information about the MC9S12DT128B device made up of standard
HCS12 blocks and the HCS12 processor core.
This document is part of the customer documentation. A complete set of device manuals also includes the
HCS12 Core User Guide and all the individual Block User Guides of the implemented modules. In a effort
to reduce redundancy all module specific information is located only in the respective Block User Guide.
If applicable, special implementation details of the module are given in the block description sections of
this document.
See Table 0-2 for names and versions of the referenced documents throughout the Device User Guide.
