What is the role of bit 9 in SCU_SCR0 ?. According to the datasheet it is reserved, however in STR91x.S from Keil examples it is set to 1. Is there an errata or something about this?

SCU_SCR0_Val EQU 0x00000196

; Setup System Configuration (and SRAM Size)

IF SCR0_SETUP == 1

LDR R0, =SCU_BASE

LDR R1, =SCU_SCR0_Val

STR R1, [R0, #SCU_SCR0_OFS]

ORR R1, #0x00000200

STR R1, [R0, #SCU_SCR0_OFS]

ENDIF

thanks,

Andras
