6.13.2 On-Chip SRAM Auto Initialization

This microcontroller allows some of the on-chip memories to be initialized through 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 TMS570LS12x/11x Technical Reference Manual (SPNU515).

The mapping of the different on-chip memories to the specific bits of the MSINENA registers is shown in

Table 6-26.

(1)

The TCM RAM interface module 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..

This is independent of whether the application chooses to initialize the MibSPIx RAMs using the system module auto-initialization

method. The MibSPIx module must be first brought out of its local reset in order to use the system module auto-initialization method.
