These functions do not directly write or read the
DS2775–DS2778. It is still necessary for the user to
store or recall this information to or from the device by
clicking the Write & Copy or Recall & Read buttons.
The Device Units (Read Only) subtab is read only. It
displays the actual hexadecimal values read from the
DS2775–DS2778 and displays the units that are stored
in the device. See Figure 25.
The Memory tab (Figure 26) gives the user access to
all 32 bytes of SRAM and all 48 bytes of EEPROM
inside the DS2775–DS2778. They are separated into
five subtabs for convenience. Any value can be modi-
fied by clicking in that address’ text box and typing a
new value in hexadecimal format. The Write button

copies the entire block of data to the corresponding
location inside the DS2775–DS2778 (scratchpad RAM
on the EEPROM blocks). The Read button updates the
entire block’s text boxes with data from the
DS2775–DS2778 (scratchpad RAM on the EEPROM
blocks). Subtabs displaying any EEPROM data also
have Copy and Recall buttons to allow the user to
transfer the data between scratchpad and EEPROM
memory internal to the DS2775–DS2778. The
Permanently Lock Block 0 and Permanently Lock
Block 1 buttons permanently store the data currently
located in that block’s EEPROM. Warning: This data
can never be changed once locked. Verify your data
first by issuing a Recall and a Read.
