Register Map Summary
The MSL3162 are controlled through an I
increments through the register map. In some cases writing to unused register addresses can cause unintended behavior
as shown in Table 4. It may be convenient to read or write to unused register address locations when accessing a block
of registers sequentially which include unused registers. The power-up default values for all control registers are stored
within on-chip user EEPROM, and any of these user EEPROM values may be changed by the user through the I
interface.
