Default address range is set according to buffer range of selected device.
Selecting option "Maintain last inserted values" causes that for the next time you open this
dialog, previously confirmed values will be reloaded as default.
The reserved key
<Shift+Ctrl+F2>
will bring out this menu from any menu and any time.
Buffer / Duplicate buffer content
This command performs duplicate buffer content in range of source EPROM to range of
destination EPROM. This procedure is suitable if there is used for example 27C512 EPROM
to 27C256 EPROM position.
Note:
The procedure always uses buffer start address 00000h.
Buffer / Checksum
Checksum of data stored in buffer of PG4UW is useful to verify that the buffer data are
correct.
PG4UW contains following functions related to checksum:
Tab
Checksum calculator
, this is on-demand
checksum calculator
that can calculate
and display various types of checksums of various data blocks in buffer. (*1)
Tab
Main checksum options
contains options for
Automatic checksum calculator
with
Main checksum
value displayed in main window of PG4UW in table
Addresses
and in
Log window
of PG4UW (*2)
Checksum calculator contains on-demand checksum calculator. (*1)
Fields
From address
and
To address
are used to enter address range for main
checksum calculation. Addresses are used only when checkbox
Enabled
is checked.
Address is always defined as Byte address.
Group
Exclude buffer block(s) from checksum calculation
is useful for example
for
serialization
. Serialization usually modifies data at specified addresses in buffer.
So there is problem to check the checksum of buffer, when data on some addresses
were changed by serialization engine before each device programming. If part of
buffer (data block) used for serialization is excluded from checksum calculation, the
checksum of buffer data will not be changed by serialization data changes. One or
more excluded blocks can be specified.
Fields displaying values of calculated
checksum types
: see description of types at
the bottom.
Column marked as
STRAIGHT
is result of checksum calculation without additional
adjustments.
Column marked as
NEGATED
is a negation of checksum so, that SUM + NEG. =
FFFFH.
Column marked as
SUPPLEMENT
is complement of checksum so, that SUM +
SUPPL. = 0 (+ carry).
Insert checksum options
box - this box contains following options for
Calculate &
insert
operation:
Insert checksum
Kind of checksum that is written into the buffer when, the
Calculate & insert operation was executed.
Insert at address
Address in buffer where a result of chosen checksum is
written, when the Calculate & insert was executed. Address
