The MCP7941X family of RTCC devices feature a
power-fail time-stamp feature. This feature will save

There are two separate sets of registers that are used
to record this information:
• The first set located at 0x18h through 0x1Bh are
• The second set of registers, located at 0x1Ch
The power-fail time-stamp registers are cleared when
