MAX13335E/MAX13336E
Dual Automotive Differential Audio Receivers
with I

C Control and Diagnostics
18
Control Register 1 (CTRL1)
Bits 7 to 2: No Function (0 should be written during write access.)
Bits 1 and 0: I2C_
The I2C1 and I2C0 bits determine the I
2
C slave address of the device. The I
2
C slave address is changed by writing to
CTRL1 while INT is pulled low (e.g., by an external microcontroller) for the duration of the I
2
C write cycle.
Diagnostic Register 0 (DIAG0)
