Because of the similarity of the QUICC SIM60 and CPU to other members of the M68300
family, such as the MC68332 and the MC68340, previous users of these devices will be
comfortable with these same features on the QUICC.

1.3.3 Software Compatibility Issues
The following list summarizes the major software differences between the MC68302 and the
QUICC:
• Pinout—The pinout is not the same. The QUICC has 240 pins; the MC68302 has 132
• Package—Both devices offer PGA and PQFP packages. However, the QUICC
• System Bus—The system bus signals now look like those of the MC68030 as opposed
• System Bus in Slave Mode—A number of QUICC pins take on new functionality in slave
• Peripheral Timing—The external timings of the peripherals (SCCs, timers, etc.) are very
• Pin Assignments—The assignment of peripheral functions to I/O pins is different in sev-
• Since the CPU32+ is a superset of the M68000 instruction set, all previously written
• The QUICC contains an 8-Kbyte block of memory as opposed to a 4-Kbyte block
• The code used to initialize the system integration features of the MC68302 has
