Copy Data [48h]
0100 1000
Copies data from all SRAM shadow registers to
EEPROM. It is recommended that a Copy Data com-
mand be performed after writing EEPROM-backed
memory locations to guarantee data integrity in the
event of a power loss. The master sends a START fol-
lowed by an address byte containing the DS7505 bus
address. The R/W bit must be a 0. The DS7505
responds with an ACK. If the next byte is a 0x48, the
DS7505 copies all Shadow RAM locations in EEPROM
memory.
Software POR [54h]
0101 0100
The master sends a START followed by an address
byte containing the DS7505 bus address. The R/W bit
must be a 0. The DS7505 responds with an ACK. If the
next byte is a 0x54, the DS7505 resets as if power had
been cycled, which stops temperature conversions and
resets all registers to their power-up states. No ACK is
sent by the IC after the POR command is received.
Afterwards, the DS7505 makes a single temperature
conversion or continuous temperature conversions,
depending on the state of the SD bit.
