NOA3302 Data Registers
NOA3302 operation is observed and controlled by internal data registers read from and written to via the external I²C
interface. Registers are listed in Table 6. Default values are set on initial power up or via a software reset command (register
0x01).
The I²C slave address of the NOA3302 is 0x37.
