A (CPU or BDM) 64 kByte local map, defined using specific resource page (PPAGE) register and the default instruction
set. The 64 Kilobytes visible at any instant can be considered as the local map accessed by the 16-bit (CPU or BDM)
address.
Run mode
MMC is functional during normal run mode.
Wait mode
MMC is functional during wait mode.
Stop mode
MMC is inactive during stop mode.
Single chip modes
In normal and special single chip mode the internal memory is used.
