The MSC1210 allows the user to partition the Flash
Memory between Program Memory and Data Memory. For
instance, the MSC1210Y5 contains 32kB of Flash
Memory on-chip. Through the HW configuration registers,
the user can define the partition between Program
Memory (PM) and Data Memory (DM), as shown in Table 3
and Table 4. The MSC1210 family offers four memory
configurations, as shown.

NOTE: Program memory accesses above the highest listed address will
access external program memory.
It is important to note that the Flash Memory is readable
and writable by the user through the MOVX instruction
when configured as either Program or Data Memory (via
the MXWS bit in the MWS, SFR 8Fh). This means that the
user may partition the device for maximum Flash Program
Memory size (no Flash Data Memory) and use Flash
Program Memory as Flash Data Memory. This may lead to
undesirable behavior if the PC points to an area of Flash
Program Memory that is being used for data storage.
Therefore, it is recommended to use Flash partitioning
when Flash Memory is used for data storage. Flash
partitioning prohibits execution of code from Data Flash
Memory. Additionally, the Program Memory erase/write
can be disabled through hardware configuration bits
(HCR0), while still providing access (read/write/erase) to
Data Flash Memory.
The effect of memory mapping on Program and Data
Memory is straightforward. The Program Memory is
decreased in size from the top of internal Program
Memory. Therefore, if the MSC1210Y5 is partitioned with
31kB of Flash Program Memory and 1kB of Flash Data
Memory, external Program Memory execution will begin at
7C00h (versus 8000h for 32kB). The Flash Data Memory
is added on top of the SRAM memory. Therefore, access
to Data Memory (through MOVX) will access SRAM for
addresses 0000h03FFh and access Flash Memory for
addresses 0400h07FFh.
Data Memory
The MSC1210 can address 64kB of Data Memory. The
MOVX instruction is used to access the Data SRAM
Memory. This includes 1,024 bytes of on-chip Data SRAM
Memory. The data bus values do not appear on Port 0
(during data bus timing) for internal memory access.
The MSC1210 also has on-chip Flash Data Memory which
is readable and writable (depending on Memory Write
Select register) during normal operation (full VDD range).
This memory is mapped into the external Data Memory
space directly above the SRAM.
The MOVX instruction is used to write the flash memory.
Flash memory must be erased before it can be written.
Flash memory is erased in 128 byte pages.
