• Description: Mpc823 Powerquicc Integrated Communications Processor For Portable Systems
• Manufacturer: Freescale Semiconductor, Inc

Endian Modes
The hardware operations that are used to support the different endian modes are:
• Address munging in the core is controlled by the MSR
• The MPC823 internal bus signal is driven by the master that informs the system
• Address munging and data bytes format in the communication processor module

interface unit to swap and perform address demunging or leave the current access as
it is. Table 10-1 defines the DC_CSR
(CPM) that is controlled by the BO field of the function code register.
