Lower Memory Register Map
Table 01h Register Map
<C> or <_/C> = Common, <D> or <_/D> = Different, <M> or <_/M> = Mixture of common and different.
Note: 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 88h). If the row is configured to exist in Table 05h, these location are empty in Table 01h.
The access codes represent the factory default values of PW_ENA and PW_ENB (Table 02h, Registers C0h–C1h).
These registers also allow for custom permissions.
