Buffer / Erase
If this command is selected, the content of the buffer will be filled with topical blank character.
The reserved key <Ctrl+F2> will bring out this menu from any menu and any time.
Buffer / Fill random data
If this command is selected, the content of the buffer will be filled with random data.
The reserved key <Shift+Ctrl+F2> will bring out this menu from any menu and any time.
Buffer / Duplicate buffer
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
The checksum dialog is used for calculate checksums of selected block in buffer. The
checksums are calculated by next way :
Byte
Word
Byte (CY)
Word (CY)
CRC-CCITT
CRC-XModem
sum by bytes to "word". CY flag is ignored
sum by words to "word". CY flag is ignored
sum by bytes to "word". CY flag is added to result.
sum by words to "word". CY flag is added to result.
sum by bytes to "word" using RESULT=PREVIOUS + (x^16 + x^12 + x^5 +1)
sum by bytes to "word" using RESULT=PREVIOUS + (x^16 + x^15 + x^2 +1)
Column marked as Neg. is a negation of checksum so, that Sum + Neg. = FFFFH.
Column marked as Suppl. is complement of checksum so, that Sum + Suppl. = 0 (+ carry).
