BDM status message (with BDM status field equal to 0b0) is sent out when the device exits BDM mode
and RCPU is in normal operating mode.
The BDM status message has the following format:
24.14.1.4 Error Message (Invalid Message)
An error message is sent out when an invalid message is received by READI. The error code within the
error message indicates that an invalid TCODE was detected in the auxiliary input messages by the signal
input formatter. Refer to
The error message has the following format:
24.14.2 RCPU Development Access Operation
The RCPU development access can be achieved either via the READI signals or the BDM signals.
To enable RCPU development access via the READI signals, the tool has to configure the DC register
during the READI reset (RSTI). Once the READI module takes the control of RCPU development access,
the protocol for transmission of development serial data in (DSDI) and out (DSDO) is performed through
the IEEE-ISTO 5001-1999 compliant vendor-defined messages.
After enabling RCPU development access via the READI signals, the READI module can enable debug
mode and enter debug mode. When debug mode is enabled and entered, READI sends a BDM status
message (BDM status field equal to 0b1) to the development tool indicating that the RCPU has entered
debug mode and is now expecting instructions from the READI signals.
The development tool then uses the DSDI Data Message to send in the serial transmission data to READI.
Data is transmitted to the tool using the DSDO data message.
This process continues until the RCPU exits debug mode and READI sends the BDM status message
(BDM status field equal to 0b0) indicating debug mode exit.
Synchronous self-clocked mode is selected by READI for RCPU development access. In this mode, the
internal transmission between READI and the USIU is performed at system frequency.
Freescale Semiconductor
Only after the DSDO data message is sent out should another DSDI data
message be sent in.
