Selecting option "Allow address history logging" activates saving of recently confirmed values.
These are saved for each device separately, count is limited to last 15 items.
Note: Address history values are common for all buffer data manipulation dialogs.
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 check the data are correct.
PG4UW contains following functions according to checksum:
? Automatic checksum calculator with Main checksum value displayed in main window
of PG4UW in table Addresses and in Log window of PG4UW
? On-demand checksum calculator that can calculate and display various types of
checksums of various data blocks in buffer.
Settings for Automatic checksum calculator and on-demand checksum calculator are
available in dialog Checksum .
Dialog Checksum contains two tabs (panels):
? Tab Main checksum options
? Tab Checksum calculator
Tab Main checksum options allows to set mode of Automatic checksum calculator .
It contains following controls:
? Checkbox Apply user-defined buffer addresses for main checksum
? unchecked status
? checked status
global Buffer start and Buffer end address is used for calculating
checksum of buffer data
user defined addresses are used to calculate checksum of buffer
data
? Fields From address and To address are used to enter address range for main
checksum calculation. Addresses are used only when checkbox Apply user-defined
buffer addresses for main checksum is checked.
? Selection group Checksum type allows selecting wished kind of checksum to be used for
main checksum. More information about Main checksum types can be found bellow.
? Field Checksum contains actual value of recently calculated checksum
? Button Apply is used to confirm checksum settings from Main checksum options. Please
note, that once the button is pressed, previous checksum settings are lost.
? Button Close is used to close the Checksum dialog.
