SNL
Serial Number Lock: Setting to a ‘1’ makes registers 10h to 17h and SNL read-only. SNL cannot be cleared once
set to ‘1’. Nonvolatile, read/write.
AL/SW
Alarm/Square Wave Select: When set to ‘1’, the alarm match drives the ACS pin as well as the AF flag. When
set to ‘0’, the selected Square Wave Freq will be driven on the ACS pin, and an alarm match only sets the AF
flag. Nonvolatile, read/write.
F(1:0)
Square Wave Freq Select: These bits select the frequency on the ACS pin when the CAL and AL/SW bits are
both ‘0’. Nonvolatile.

VBC
VBAK Charger Control: Setting VBC to ‘1’ (and FC=0) causes a 80 A (1 mA if FC=1) trickle charge current to
be supplied on VBAK. Clearing VBC to ‘0’ disables the charge current. Battery-backed, read/write.
FC
Fast Charge: Setting FC to ‘1’ (and VBC=1) causes a ~1 mA trickle charge current to be supplied on VBAK.
Clearing VBC to ‘0’ disables the charge current. Battery-backed, read/write.
VTP(1:0)
VTP Select. These bits control the reset trip point for the low-VDD reset function. When VDD is below the
selected VTP voltage, the reset pin /RST will drive low and the SPI interface will be locked out. Nonvolatile,
read/write.
