25.14.8 NZ6C3 Read/Write Access to Memory-Mapped Resources
The read/write access feature allows access to memory-mapped resources via the JTAG/OnCE port. The
read/write mechanism supports single as well as block reads and writes to e200z6 system bus resources.
The NZ6C3 module is capable of accessing resources on the e200z6 system bus, with multiple
configurable priority levels. Memory-mapped registers and other non-cached memory can be accessed via
the standard memory map settings.
All accesses are setup and initiated by the read/write access control/status register (RWCS), as well as the
read/write access address (RWA) and read/write access data registers (RWD).
Using the read/write access registers (RWCS/RWA/RWD), memory-mapped e200z6 system bus resources
can be accessed through NZ6C3. The following subsections describe the steps which are required to access
memory-mapped resources.
NOTE
Read/write access can only access memory mapped resources when system
reset is de-asserted.
Misaligned accesses are NOT supported in the e200z6 Nexus3 module.
