Copy Scratchpad [48hxxh]
This command copies the scratchpad page xxh into the EEPROM / SRAM memory page xxh of the
DS2437. After issuing this command, the user must write a page number to direct which page of memory
the scratchpad is to be copied. Valid page numbers are 00h - 07h. If the bus master issues read time slots
following this command, the DS2437 will output 0 on the bus as long as it is busy copying the scratchpad
to SRAM/EEPROM; it will return a 1 when the copy process is complete.
Recall Memory [B8hxxh]
This command recalls the stored values in EEPROM/SRAM page xxh to the scratchpad page xxh. This
command must procede a Read SPxx command in order to read any page of memory on the DS2437. No
data is available directly with a Read SP command. Valid page numbers are 00h - 07h.
Convert T [44h]
This command begins a temperature conversion. No further data is required. The temperature conversion
will be performed and then the DS2437 will remain idle. If the bus master issues read time slots
following this command, the DS2437 will output 0 on the bus as long as it is busy making a temperature
conversion; it will return a 1 when the temperature conversion is complete.
Convert V [B4h]
This command instructs the DS2437 to initiate a voltage analog-to-digital conversion cycle. The voltage
supply that is measured is defined by the AD bit of the Status/Configuration register. This sets the ADB
flag (see Status/Configuration register discussion in the Memory Map section). When the A/D conversion
is done, the ADB flag is cleared and the current voltage value is placed in the VOLTAGE REGISTER of
page 00h. While an A/D conversion is taking place, all other memory functions are still available for use.
If the bus master issues read time slots following this command, the DS2437 will output 0 on the bus as
long as it is busy making a voltage measurement; it will return a 1 when the conversion is complete.
