• Manufacturer Part Number: ds1876
• Description: Sfp Controller With Dual Ldd Interface
• Manufacturer: Maxim Integrated Products, Inc.

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.
Note: Table 05h is empty by default. It can be configured to contain the alarm and warning enable bytes from Table 01h,
Registers F8h–FFh with the MASK bit enabled (Table 02h, Register 88h). In this case Table 01h is empty.
<C> or <_/C> = Common, <D> or <_/D> = Different, <M> or <_/M> = Mixture of common and different.
<C> or <_/C> = Common, <D> or <_/D> = Different, <M> or <_/M> = Mixture of common and different.
