Table 02h Register Map
Table 04h Register Map
<C> or <_/C> = Common, <D> or <_/D> = Different, <M> or <_/M> = Mixture of common and different.
*The final result must be XORed with BB40h before writing to this register.
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.
<C> or <_/C> = Common, <D> or <_/D> = Different, <M> or <_/M> = Mixture of common and different.
