34.3.6 System Information Block

The System Information Block (SIB) can be read out at any time by setting the SIB bit in the KEY instruction from 34.3.3.8 KEY - Set Activation KEY. The SIB provides a compact form of providing information for the debugger, which is vital in identifying and setting up the proper communication channel with the part. The output of the SIB should be interpreted as ASCII symbols. The KEY size field should be set to 16 bytes when reading out the complete SIB, and an 8-byte size can be used to read out only the Family_ID. See Figure 34-19 for SIB format description, and which data is available at different readout sizes.
