S12G Memory Map Controller (S12GMMCV1)
5.1
The S12GMMC module controls the access to all internal memories and peripherals for the CPU12 and
S12SBDM module. It regulates access priorities and determines the address mapping of the on-chip
resources.
5.1.1
5.1.2
The S12GMMC connects the CPU12’s and the S12SBDM’s bus interfaces to the MCU’s on-chip resources
(memories and peripherals). It arbitrates the bus accesses and determines all of the MCU’s memory maps.
Furthermore, the S12GMMC is responsible for constraining memory accesses on secured devices and for
selecting the MCU’s functional mode.
