3.2 MC68HC912DT128A Pin Assignments in 112-pin QFP
The MC68HC912DT128A is available in a 112-pin thin quad flat pack
(TQFP). Most pins perform two or more functions, as described in the
Signal Descriptions. Figure 3-1 shows pin assignments. In expanded
narrow modes the lower byte data is multiplexed with higher byte data
through pins 57-64.
