Freescale Semiconductor

21

•

Controls arbitration between e200Z6 and e200Z0 Nexus modules to the Nexus Auxiliary output

port

•

Generates full port mode indication output port

•

Generates MCKO and frequency division (1/2, 1/4, 1/8).

•

Controls sharing of EVTO/EVTI

•

Enables gating of MCKO when the auxiliary output port is idle.

e200Z6 development support features (Nexus class3)

•

IEEE-ISTO 5001-2003 standard class 3 compliant

•

Program trace via branch trace messaging (BTM)

•

Data trace via data write messaging (DWM) and data read messaging (DRM). This allows the

development tools to trace reads and /or writes to selected internal memory resources

•

visibility of which process ID or operating system task is activated

•

Run-time access to the e200Z6 memory map via the JTAG port

•

Watchpoint messaging

•

Watchpoint trigger enable of program and/or data trace messaging
