Chapter 1 MC9S12KT256 Device Overview (MC9S12KT256V1)
1.2 Signal Description
The MC9S12KT256 is available in a 112-pin low profile quad flat pack (LQFP) and a 80-pin quad flat pack
(QFP). Most pins perform two or more functions, as described in Section 1.2.1, “Signal Properties
Summary”. Figure 1-3 and Figure 1-4 show the pin assignments for different packages.
