Description
C-2
C.1 Description
The MSC1210 has a 2K ROM. This code provides the interaction for serial and
parallel programming. There are also several routines that are useful and nec-
essary for use with user applications. For example, when writing to flash
memory, the code cannot execute out of flash memory. By calling the flash
write routine in ROM, this condition is satisfied. Convenient access to those
routines is supplied through a jump table summarized in Table C−1.
