Memory Auto-Initialization

This device allows some of the on-chip memories to be initialized via the memory hardware initialization

control registers in the System module. The purpose of having the hardware initialization is 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. Please refer to the Architecture chapter

of the Technical Reference Manual (TRM) for more information.

The mapping of the different memories to the specific bits in the MSINENA register is shown in the

following table.

reserved only; the FlexRay RAM has its own Initialization mechanism.

The associated ECC RAM will get initialized as well, if the ECC functionality is enabled.

The associated Parity RAM will get initialized as well, if the Parity functionality is enabled.

NOTE

The user must initialize entire SRAM with ECC bits to avoid ECC errors due to Cortex R4

speculative fetches if SRAM ECC is enabled.
