2.1 Description
The MCS1210 has three very general types of memory. To program the
MCS1210 effectively, it is necessary to have a basic understanding of these
memory types:
- Special Function Registers refer to 128 bytes that control the operation
of the MSC1210.
- Program Memory is used to store the actual program that may reside on-
chip, off-chip, or both.
- Data Memory is static random access memory (SRAM) that can reside
on-chip, off-chip, or both. The MSC1210 has four types of data memory:
J On-chip extended SRAM
J Off-chip external SRAM
J On-chip Flash Data memory
J Internal RAM
2.2 Program Memory
Program memory holds the actual program that is to be run. This memory in-
cludes the on-chip flash memory designated as program memory and/or ex-
ternal memory.
The MSC1210 family offers a maximum of 32k of on-chip flash program
memory. The exact amount of on-chip program memory depends on the spe-
cific MSC1210 version selected and how the flash memory of that chip has
been partitioned between program and data memory. Figure 2−1 illustrates
how the flash memory may be distributed between these two types of memory.
