FUNCTIONAL BLOCK REQUIREMENTS AND BEHAVIORS
6.5.5
Specific registers
6.5.5.1
IC and version identification
The IC and other version details can be read via identification bits. These are hard-wired on chip and described in Tables 128 to 130.
6.5.5.2
Embedded memory
There are four register banks of general purpose embedded memory to store critical data. The data written to MEMA[7:0], MEMB[7:0],
MEMC[7:0], and MEMD[7:0] is maintained by the coin cell when the main battery is deeply discharged, removed, or contact-bounced. The
contents of the embedded memory are reset by COINPORB. The banks can be used for any system need for bit retention with coin cell
backup.
