RCPU development access can be achieved either via the READI signals or the BDM signals on the MCU.
The access method is determined during READI module configuration.
and BDM signals are multiplexed for RCPU development access.
When the READI module is configured for RCPU development access, IEEE-ISTO 5001 compliant
vendor-defined messages are used for transmission of data in and out of the MCU.
24.14.1 RCPU Development Access Messaging
The following RCPU development access messages are used for handshaking between the device and the
tool — DSDI data message, DSDO data message, and BDM status message.
24.14.1.1 DSDI Message
The DSDI message is used by the tool to download information to the RCPU.

On the MPC561/MPC563 the BDM signals are shared with the READI
signals. Therefore BDM access is limited to access via the Nexus
vendor-defined development support messages.
