The System Information Block (SIB) can be read out at any time by setting the SIB bit according
to the KEY instruction from the KEY - Set Activation Key or Send
System Information Block section. The SIB is always accessible to the debugger,
regardless of lock bit settings, and provides a compact form of supplying information
about the device and system parameters for the debugger. The information is vital in
identifying and setting up the proper communication channel with the device. The output
of the SIB is interpreted as ASCII symbols. The key size field must 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 37-18 for SIB format description
and which data are available at different readout sizes.Figure 37-18. System Information Block
