MC68HC912BL16TS/D
* In narrow mode, high and low data bytes are multiplexed in alternate bus cycles on port A.
PAI / IOC7 / PT7
The MC68HC912BL16 is available in a 64-pin quad flat pack (QFP). Most pins perform two or more
functions, as described in the 3.3 Signal Descriptions. Figure 3 shows pin assignments. Shaded pins
are power and ground.
