STATUS REGISTER
The default values for the Status Register bits are stored in lockable EEPROM in the corresponding bits of address
31h. A Recall Data command for EEPROM block 1 recalls the default values into the Status Register bits. The
format of the Status Register is shown in Figure 15. The function of each bit is described in detail in the following
paragraphs. Note that all bits are Read Only.
Figure 15. STATUS REGISTER FORMAT
PIE1, PIE0—Programmable Suspend Interrupt Enable. A non zero value in these bits enables the DS2756 to enter
Suspend mode, and sets the Suspend Period (t
DS2756 from entering Suspend mode and allows the DS2756 to enter Sleep mode.
*Each EEPROM block is read/write until locked by the LOCK command, after which it is read-only.
