8. Control Registers
The control registers can be divided into three main classes: Initialization, Run-time, and Status. Initialization
registers (“I”) need only be programmed once following device power-up. Run-time registers (“RT”) are the primary
registers for device control. Status registers (“S”) provide device state information. The corresponding category of
each register is indicated in the rightmost column of Table 19.
Unused register bits of a register byte are reserved, Their bit values should not be changed from the default values,
as identified below under the description of each individual register byte.
Table 18 lists all registers available in Si2110; some registers may not be available in other part versions, as
identified below under the description of each individual register byte.
