The System Information Block (SIB) can be read out at any time by setting the SIB bit according
to the KEY instruction from 32.3.3.8 KEY - Set Activation Key or
Send System Information Block. 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 32-19 for SIB format description and which data are available at different
readout sizes.Figure 32-19. System Information Block
