4.9 Low Battery Configuration Registers (LBCFG)
Page 0x01, 0x05 - LBCFG05 [default 0xB1]
Page 0x01, 0x06 - LBCFG06 [default 0x96]
Note: take care to immediately return to configuration register memory map page 0 following a read or write to
the low battery configuration registers in page 1. Page configuration register PGCFG1F is mapped into all pages
at the same address of 0x1F. Bits 0..1 of this register control page selection. See Table 46.
