4.13.2 On-Chip SRAM Auto Initialization
This microcontroller allows some of the on-chip memories to be initialized to zero via the Memory
Hardware Initialization mechanism in the System module. This hardware mechanism allows an application
to program the memory arrays with error detection capability to a known state based on their error
detection scheme (odd/even parity or ECC).
The MINITGCR register enables the memory initialization sequence, and the MSINENA register selects
the memories that are to be initialized.
For more information on these registers see the device specific technical reference manual.
The mapping of the different on-chip memories to the specific bits of the MSINENA registers is shown in
Table 4-26. Memory Initialization

(1)
The TCM RAM wrapper has separate control bits to select the RAM power domain that is to be auto-initialized.
(2)
The MibSPIx modules perform an initialization of the transmit and receive RAMs as soon as the module is released from its local reset
via the SPIGCR0 register. This is independent of whether the application chooses to initialize the MibSPIx RAMs using the system
module auto-initialization method. Before the MibSPI RAM can be initialized using the system module auto-initialization method: (i) The
module must be released from its local reset, AND (ii) The application must poll for the "BUF INIT ACTIVE" status flag in the SPIFLG
register to become cleared (zero)
