; Initialize 64kByte block first 
Data.Set 0--0xffff %Long 0

; Assemble SDRAM initialization routine
;
; Initialization routine is writing to whole SDRAM except the 
; first 64 kByte initialized already above.
;
Data.Assemble 0x1000 mov r2,#0
Data.Assemble 0x1004 str r2,[r0],#0x04
Data.Assemble 0x1008 cmp r0,r1
Data.Assemble 0x100c bne 0x1000
; Setup register for initialization routine
Register.Set r0 0x10000		; Initialization start
Register.Set r1 0x10000000	; size of SDRAM
Register.Set PC 0x1000		; set PC to Initialization routine
; Execute initialization routine
Go.direct 0x1010
SCREEN.display
WAIT !STATE.RUN()

; Enable ECC
Data.Set 0FFFFE51C %Long 00000008
WAIT 5.ms

; Initialize 64kByte block again to clear initialization routine 
Data.Set 0--0xffff %Long 0
