2.2 Non-volatile read/write
In addition, the Power Amplifier contains 256 bytes of non-volatile read/write memory for
storing phase control and attenuation levels for various channel frequencies. The manufacturer
will be responsible for initializing correct attenuation & phase values for all frequencies, as well
as model and version numbers.
The memory content and locations are defined in Table 2-2:
