8.3 RAM
Internal static RAM is for control registers, data RAM, stack RAM and the LCD frame buffer.
8.3.1 Control Registers
8.3.2 Data RAM ($0080~$09FF)
Data RAM are organized in 2432 bytes from $0080~$08FF.
8.3.3 Stack RAM ($0100~$01FF)
Stack RAM is organized in 256 bytes. It provides for a maximum of 128-level subroutine stacks and can be used as data memory.
8.3.4 LCD Frame Buffer ($1000~$10AF)
LCD frame buffer is accessible by both read/write instructions and LCD controller. Note that this area can also be used as data
memory. Each pixel of LCD panel is directly mapped into this area. Refer to section 15.3 for the detail mapping.
