24.10 Read/Write Access
The read/write access feature allows access to internal memory-mapped space via the auxiliary port.
Read/write mechanism supports single and block, reads and writes.
24.10.1 Functional Description
The READI module is capable of bus mastership on the L-bus and for setting up and reading data and
status.
All accesses are setup and initiated to the read/write access register (RWA) and upload/download
information register (UDI) via the four auxiliary access public messages: device ready for
upload/download, upload request (tool requests information), download request (tool provides
information), upload/download information (device/tool provides information).
Read/write access features are enabled by setting the appropriate fields in the RWA register. For details on
field configuration, refer to
The functional flow for read/write access to memory-mapped locations and MPC500 registers is depicted
