NOTE: The user, utilizing the COP8TAx9 Flash based de-
vices during development, is cautioned to ensure that code
contains NO calls to Boot ROM functions prior to submission
for ROM generation. Instances of the JSRB instruction in
ROM based devices will be executed as a JSR instruction to
a location in the first 256 bytes of Program Memory.
Flash and ROM devices are not 100% identical. The execu-
tion of the JSRB instruction is an example of the potential

strongly advised to obtain masked ROM prototype devices
before committing to production quantities. This will allow the
