Error information is messaged out in the following format:
Figure 25-53. Error Message Format
25.14.9 Examples
The following are examples of program trace and data trace messages.
Table 25-40 illustrates an example indirect branch message with an 8 MDO and 2 MSEO configuration.
Note that T0 and S0 are the least significant bits where:
• Tx = TCODE number (fixed)
• Sx = Source processor (fixed)
• Ix = Number of instructions (variable)
• Ax = Unique portion of the address (variable)
Table 25-41 illustrates an example of direct branch message with 12 MDO and 2 MSEO.
Note that T0 and I0 are the least significant bits where:
• Tx = TCODE number (fixed)
• Sx = Source processor (fixed)
• Ix = Number of instructions (variable)
