Section 3
Central Processing Unit
This chapter is an overview of the processor logic on the Pm8560. It includes information
on the CPU, exception handling, and the I/O parallel port pin assignments. The Pm8560
uses a Freescale MPC8560 PowerQUICC III™ microprocessor. For more detailed informa-
tion, refer to the
MPC8560
PowerQuicc III Integrated Communications Processor Reference
Manual
. The MPC8560 is divided into three main system blocks as outlined in the following
table:
