22 / 138 page  MC9S12DT128 Device User Guide — V02.09 22 – Port K Port K pull-up resistors are enabled out of reset, i.e. Bit 7 = PUKE = 1 in the register PUCR at Base+$000C. Therefore care must be taken not to clear this bit. – Port M[1:0] PM1:0 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[3:2] PS3:2 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 MC9S12DT128 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 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.
