Computes a 16 Bit
Cksum of the currently
selected sector from
the first byte until
<pos> (the byte at the
specified position is
included). This Cksum
has to match with the
expected value (i.e. of
the new firmware
sector)
- If this Cksum
differs from expected
results data is
corrupted, which can
result in an
unreachable device.
- In case a wrong
cksum was reported,
the whole sector has
to be erased (see
next command)
- Note: If just a part
of a sector needs to
be written, the
specified position
should be the last byte
written. If the
maximum value
(0xFFFF) is specified,
trailing 0xFF's inside
this sector would be
also used for
calculation.
- Do not specify
0xFFFF for the very
last sector containing
a configuration
- the maximum value
for this sector is
0x7FFF.
