Freescale Semiconductor
The DSDI data field has a 3-bit status header followed by 7 or 32 bits of data/instruction, depending on
the RCPU development port mode.
The DSDI message has the following format:
Figure 24-79. DSDI Message Format
NOTE
When sending in a DSDI data message, the DSDI data should contain the
control and status bits (start, mode, control), followed by the 7 or 32-bit
CPU instruction/data or trap enable, MSB first. See
for DSDI
data message transmission sequence.
24.14.1.2 DSDO Message
The DSDO message is used by the device to upload information from the RCPU.
The DSDO data field has a 3-bit status header followed by 7 or 32 bits of data/instruction, depending on
the RCPU development port mode.
The three status bits in the DSDO data indicates if the device is ready to receive the next message from the
tool.
The DSDO message has the following format:
Figure 24-80. DSDO Message Format
NOTE
The DSDO data received will contain the control and status bits and data
from the CPU, MSB first. See
for DSDO data message
transmission sequence.
24.14.1.3 BDM Status Message
BDM status message is generated by the device to let the tool know about the status of debug mode.
BDM status message (with BDM status field equal to 0b1) is sent when the RCPU is in debug mode and
the device is ready to receive debug mode messages.
