G
Program the FCR register
with a value that selects the desired operating mode. Note that this
does not yet start the programming operation itself.
MOV

μ
s programming pulse (fCPU = 20 MHz)

MOV
DPP1:pof FCR, R15
; Write Value to the FCR using 16-bit access
G
Initialize pointers and counter
for the first transfer of the programming algorithm.
The source data block is accessed via the pointer SRC_PTR, initialized with SRC_START. All
read operations via SRC_PTR use DPP2, which selects data page 1 in this example.
The Flash memory must be accessed indirectly and uses the pointer FLASH_PTR, initialized
with FLASH_START.
The counter DWCOUNT defines the number of doublewords to be programmed.
G
Test for correct V
PP
margin at pin V
PP
/EBC1
before a programming operation is started. If bit
VPPREV reads ‘1’, the programming voltage is correct and the algorithm can be continued.
Otherwise, the programming routine could wait in Flash writing mode until V
PP
reaches its correct
value and resume programming then, or it could exit writing mode.
MOV
