Description

SRAM arbitration and protection

Fields

SRAMUAP

SRAM_U arbitration priority

0 (00): Round robin

1 (01): Special round robin (favors SRAM backoor accesses over the processor)

2 (10): Fixed priority. Processor has highest, backdoor has lowest

3 (11): Fixed priority. Backdoor has highest, processor has lowest

SRAMUWP

SRAM_U write protect

SRAMLAP

SRAM_L arbitration priority

0 (00): Round robin

1 (01): Special round robin (favors SRAM backoor accesses over the processor)

2 (10): Fixed priority. Processor has highest, backdoor has lowest

3 (11): Fixed priority. Backdoor has highest, processor has lowest

SRAMLWP

SRAM_L write protect
