Internal static RAM can be divided into 3 parts in function. First
is the zero page memory, second is for stack, and third can be
used as LCD frame buffer or for general purpose.
Zero Page Data RAM ($0080~$00FF)
Total 128 bytes of data RAM in zero page is very useful for
programmers. They provide short instruction codes and cycles.
Use zero page addressing mode on the variables in this area
usually speeds up the overall performance.
Stack RAM ($0100~$01FF)
The ST2202 has 256 bytes stack from $0100 to $01FF. It
provides a maximum of 128 levels for subroutines. By setting
stack pointer carefully, stack memory can also be used as data
memory.
User Memory and LCD Frame Buffer
($0200~$0FFF)
The ST2202 shares memory for both user memory and LCD
frame buffer. The range of LCD frame buffer will be fixed after
initialization of LCD control registers. Memory beyond is user
memory. Read and write operations can be applied to LCD
frame buffer to maintain display content, and almost none of
the CPU time is affected. This is contributed by one special
memory transfer technique of display data from LCD frame
buffer to the LCD controller.
