Table 05h Register Map
<C> or <_/C> = Common, <D> or <_/D> = Different, <M> or <_/M> = Mixture of common and different.
Note: Table 05h is empty by default. It can be configured to contain the alarm and warning enable bytes from Table 01h,
Registers F8hFFh with the MASK bit enabled (Table 02h, Register 88h). In this case Table 01h is empty.
Auxiliary Memory A0h Register Map
The access codes represent the factory default values of PW_ENA and PW_ENB (Table 02h, Registers C0hC1h).
These registers also allow for custom permissions.
<C> or <_/C> = Common, <D> or <_/D> = Different, <M> or <_/M> = Mixture of common and different.
