3.4 Pin Descriptions
3-8
MOTOROLA
Table 3-1 summarizes pin characteristics of the MC68HC16Y3 and MC68HC916Y3
MCUs. Entries in the “Associated Module” column indicate to which module individual
pins belong. For MCU pins that can be outputs, the “Driver Type” column lists which
output driver type is used. Table 3-2 briefly describes the four primary driver types. A
“—” in the “Driver Type” column indicates either that the pin is an input only, and thus
does not have a driver, or that the pin has a special driver, like the XTAL pin. Entries
in the “Synchronized Input” and “Input Hysteresis” columns denote whether MCU pins
that can be inputs are synchronized to the system clock and if they have hysteresis.
Pins that are outputs only or that have special characteristics, like the EXTAL pin, have
a “—” in these columns.
