Memory
4.1 Memory Map
The memory map of the MCU is divided into the following groups:
⢠Fast access RAM using tiny and short instructions ($0000â$000E1)
⢠Indirect data access D[X] ($000E)
⢠Index register X for D[X] ($000F)
⢠Frequently used peripheral registers ($0010â$001E)
⢠PAGESEL register ($001F)
⢠RAM ($0020â$004F)
⢠Paging window ($00C0â$00FF)
⢠Other peripheral registers ($0200â$023F)
⢠Nonvolatile memory
â MC9RS08KA2: $3800â$3FFF
â MC9RS08KA1: $3C00â$3FFF
1. Physical RAM in $000E can be accessed through the D[X] register when the content of the index register X is $0E.
