B.1 Introduction
The MC68HC908AZ60E is a reduced EMC version of the MC68HC908AZ60A. Every care has been
taken to insure compatibility with the MC68HC908AZ60A. Some additional features are available,
however the default state of all affected modules match the MC68HC908AZ60A functionality. The reset
state of all MC68HC908AZ60E registers match the MC68HC908AZ60A except for some reserved
memory locations. Although significant design changes have been made to improve the radiated RF
emissions from the MCU, all electrical specifications are equal to or better than the MC68HC908AZ60A.
Slew rate controlled outputs have been added to all the general purpose I/O pins as well as the
PTC2/MCLK, PTE5/MISO, PTE6/MOSI, and PTE7/SPSCK pins.
