SPECIAL PROPERTIES
memory
read-write, binary
8192 bytes of memory. Initially all bits are set to 1. Writing zero
permanently alters the memory.
pages/page.0 ... pages/page.255 pages/page.ALL
read-write, yes-no
Memory is split into 256 pages of 32 bytes each. ALL is an aggregate of
the pages. Each page is accessed sequentially.
STANDARD PROPERTIES

ALARMS
None.
DESCRIPTION
See the file man3/description.3so.
DS2506 DS1986
The DS2506 (3) is used for write-once incremental storage. It's main advantage is for audit trails (i.e. a digital purse).
The DS2506-UNW is one of the UniqueWare class of devices. Some of the memory was preprogramed at the factory. See the datasheet for specifics. The DS2502 , DS2505 , and DS2506 differ in their function by the amount of on-board memory they possess. (The internal protocols are slightly different, but the OWFS system handles this automatically.
ADDRESSING
See the file man3/addressing.3so.
