4.14.2 On-Chip SRAM Auto Initialization
This microcontroller allows some of the on-chip memories to be initialized 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 refer to the device Technical Reference Manual.
The mapping of the different on-chip memories to the specific bits of the MSINENA registers is shown in

The MibSPI1 module performs an initialization of the transmit and receive RAMs as soon as the module is brought out of reset using the
SPI Global Control Register 0 (SPIGCR0). This is independent of whether the application chooses to initialize the MibSPI1 RAMs using
the system module auto-initialization method.
