Programming a block of data
The following code is provided as an example to program a block of data. Flash to be programmed is from
address 01’9000h to 01’9FFEh (included). Source data (data to be copied into flash) is located in external
RAM from address 05’1000h (to 05’1FFEh, implicitly) :
; code shown below assumes that flash is mapped in segment 1
; ie. bit ROMS1 = ‘1’ in SYSCON register
; Flash must be enabled, ie. bit ROMEN = ‘1’ in SYSCON.

DPP2
; AA5xh : Multi Word programming command
; Selects segment 1 in Flash memory
; First Flash Segment Offset Address
; Last Flash Segment Offset Address
; Source data address: use DPP2 as
; data page pointer
; Source is in page 20 (first page of
; segment 5): save previous DPP2 value
; and load it with source page number
; 50ns is 20MHz CPU clock frequency
; R7 used for Flash trigger sequence
; Flash can be mapped in segment 0 or 1
; first part
; second part
; WARNING: place 2 NOP operations after
; the Unlock sequence to avoid all possible
; pipeline conflicts in STEAK programs
; restore DPP2
