61 / 86 page  3–5 3.5 Writing Data Into the EPROM When data is written into the EPROM address range, software code is written into RAM locations 214h to 23Dh. All addresses 1000h or higher are assumed to be EPROM. After the write operation is completed, the code in the RAM is no longer needed. The code is written into RAM when a write into the EPROM address range is performed. Ensure that the data in these locations are not needed when the EPROM write code is temporarily loaded into those locations. A write into EPROM can be done when an application program is executed, or when the monitor is active. For example, when the mx[n] command is executed: Available RAM for User Application RAM Area Always Reserved for ROM Monitor 214h 212h 200h RAM Area Always Reserved for ROM Monitor 212h 214h 200h Temporary Burn Routine 23Dh 23Eh Available RAM for User Application No write to EPROM active Figure 3–4. Temporary Burn Routine in the MSP430x32x RAM Area User application data for the MSP430X33x family should be located within the RAM area (from 200h to 5FFh). The locations used statically (200h to 214h), and dynamically (stack) by the Monitor Program limit the size of the available RAM. NOTE: The Identification Bit Pattern defines if the monitor code or a user’s code (program) is executed after a power-up or hardware reset (PUC). See Section 5.2. The Temporary Burn Routine user’s addresses are allocated for the EPROM burn routine which must run in the RAM. When data is written into the EPROM (program memory), code in the EPROM can not be executed. Therefore, the burn program has to be in the RAM (loaded from the EPROM so it can be executed). |
