The value of this read-only register indicates the production
version of the IC (0x0011).

• RCOMP compensates the model for different lithium
• SLEEP forces the IC in or out of sleep mode. Writing
• ALRT (alert status bit) is set by the IC when SOC
• ATHD (empty alert threshold) sets the SOC threshold,
