;- Internal RAM Definition
;--------------------------
; The Internal SRAM is redefined in two blocks (248K + 8K) due to the EB40A has no External SRAM. 
; The 8K (from 0x0 to 0x01FFF) are for Vector table and Exception stack defined by RAM_LIMIT.
; The 248K (from 0x2000 to 0x3FFFF) are for User Application code and Application stack defined by EXT_SRAM_LIMIT

RAM_BASE   		EQU     0x00000000		;    @- Address of the Internal SRAM after the remap command
RAM_SIZE		EQU		8*1024		;      

; **************
; * WARNING !!!*  The RAM_LIMIT definition does not correspond to ( RAM_BASE + RAM_SIZE )
; ************** 

; - This is for compatipility with the cstartup_xxx.ads (flash, ice or angel).
RAM_LIMIT		EQU		(RAM_BASE + (8*1024)) ; @ The size of the Application stack is 8K.

; The internal RAM is mapped at address 0x00300000 after reset until
; Remap command is performed on the EBI.

;- EBI Initialization Data          
;-------------------------
;- The EBI User Interface Image which is copied by the boot.
;- 66MHz master clock assumed.
;- That's hardware! Details in the Electrical Datasheet of the AT91 device.
;- EBI Base Address is added at the end for commodity in copy code.
;-
;- EBI_CSR_1 configuration is removed because no external SRAM is fitted on the board. If External SRAM is added,
; replace with the line below the EBI_CSR1 line.
