Texas Instruments MSC1210 Table C−1. Boot ROM Routines, Address Routine Declarations Description

Description

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.
