4. Initial default boot core that executes code from the Boot Assist Flash (BAF). Debuggers have access to this core initially

as well.

2 Differences between MPC57xx e200zx cores

The second major generation of the e200zx cores has minor variations for different devices. The following sections show all
of the devices in the MPC57xx family and the variations of the cores used in each device (and version). The core options
have been divided into three sections:

• Core instruction set and execution options (signal processing instruction options, saturated math instructions, floating

point type options, instruction issue option, lock-step option etc.).

• Core bus interface options (memory protection options, end-to-end error correction code options, crossbar bus width,

local memory options, and cache options)

• Core debug options (Nexus class, timestamp option, trace port width, and whether it has the fixed JTAG Nexus register

access sequence)

The tables in the following sections are arranged by core complexity. The e200z210 is the "simplest" core (feature-wise) and
with the e200z759 being the most complex.

2.1 e200zx core execution options

The first set of options that are available to be integrated into the cores instantiated into a particular MCU directly affect the
cores, including what instructions are supported and how the instructions execute. These options are shown in the following
table, then each of the options is explained in more detail.
