Table 3-3. MC68HC912DT128A Port Description Summary
Register (Address)
When the PUPT bit in the TMSK2 register is set, all input pins are pulled
up internally by an active pull-up device. Pullups are disabled after reset.
Setting the RDPT bit in the TMSK2 register configures all port T outputs
to have reduced drive levels. Levels are at normal drive capability after
reset. The TMSK2 register can be read or written anytime after reset.
