6 Control and Status Registers
Table 31 shows the 73M1x66B register map of addressable registers. The shaded cells indicate read-only
bits and cannot be modified. Reserved bits should be left in their default state. Accessing unspecified
registers should be avoided. Each register and bit is described in detail in the following sections.
For registers 0x12 through 0x1F, which are located in the Line-Side Device, there is a minimum time
between consecutive write transactions of 300 µs when using an 8 kHz sample rate.
