Architecture
(1)
If parity protection is enabled for the peripheral SRAM modules, then the parity bits will also be initialized along with the SRAM
modules.
(2)
If ECC protection is enabled for the CPU data RAM or peripheral SRAM modules, then the auto-initialization process also
initializes the corresponding ECC space.
(3)
The level 2 SRAM range from 128kB to 512kB is divided into 6 memory regions. Each region has an associated control bit to
enable auto-initialization.
(4)
The MibSPIx modules perform an initialization of the transmit and receive RAMs as soon as the multi-buffered mode is enabled.
This is independent of whether the application has already initialized these RAMs using the auto-initialization method or not. The
MibSPIx modules need to be released from reset by writing 1 to their SPIGCR0 registers before starting auto-initialization on
their respective RAMs.
