The built-in bootstrap loader of the C161U provides a mechanism to load the startup
program, which is executed after reset, via the serial interface.
The bootstrap loader moves code/data into the internal RAM, but it is also possible to
transfer data via the serial interface into an external RAM using a second level loader
routine. It may be used to provide lookup tables or may provide “core-code”, ie. a set of
general purpose subroutines, eg. for I/O operations, number crunching, system
initialization, etc.
Figure 111
The Bootstrap Loader may be used to load the complete application software into
ROMless systems, it may load temporary software into complete systems for testing or
calibration.
