# [SPECIAL PROPERTIES](#SPECIAL_PROPERTIES)

## [lock.\[0-1|ALL\]](#lock._0-1_ALL_)

*read-write, yes-no*  
Lock either of the two eprom pages to prevent further writes. Apparently setting *lock* is permanent.

## [memory](#memory)

*read-write, binary*  
Access to the full 256 byte memory range. Much of this space is reserved or special use. User space is the *page* area.  
See the *DATASHEET* for a full memory map.

## [pages/pages.\[0-1|ALL\]](#pages/pages._0-1_ALL_)

*read-write, binary* Two 8 byte areas of memory for user application. The *lock* property can prevent further alteration.  
NOTE that the *page* property is different from the common *OWFS* implementation in that all of *memory* is not accessible.

# [OBSCURE PROPERTIES](#OBSCURE_PROPERTIES)

## [cc ce dc de doc ot ov uv](#cc_ce_dc_de_doc_ot_ov_uv)

*varies, yes-no*  
Bit flags corresponding to various battery management functions of the chip. See the *DATASHEET* for details of the identically named entries.  
In general, writing "0" corresponds to a 0 bit value, and non-zero corresponds to a 1 bit value.
