The ALARM ENABLE bytes (Registers F8h–FFh) can be configured to exist in Table 05h instead of here at Table 01h
with the MASK bit (Table 02h, Register 89h). If the row is configured to exist in Table 05h, then these locations are
empty in Table 01h.
The access codes represent the factory default values of PW_ENA and PW_ENB (Table 02h, Registers C0h–C1h).
