NOTE:
—
Rev. 1.1
Programming of the FLASH memory is done on a row basis. A row
consists of 32 consecutive bytes starting from addresses $XX00,
$XX20, $XX40, $XX60, $XX80, $XXA0, $XXC0 or $XXE0. Use this
step-by-step procedure to program a row of FLASH memory:
(Figure 4-2
In order to avoid program disturbs, the row must be erased before any
byte on that row is programmed.
This program sequence is repeated throughout the memory until all data
is programmed.
