detailed description (continued)
register programming
The TLV320AIC22 contains 17 registers that are used to configure the device for the desired operation. Register
programming can be accomplished in two different ways:
D The serial interface (time slots 0 and 1)
D The I2C bus
The I2C/SPI pin is used to select either interface for programming the device.
register programming using the serial interface
To program the control registers using the serial interface, the I2C/SPI pin should be tied to logic 0. The frame
format and control-word description are discussed in serial interface earlier in this document.
Time slots 0 and 1 are used for codec register programming and are configured as follows:
D Slot 0: Read/write, physical address of codec register
This is the register address, appended to the codec address, derived from pins AD0 and AD1.
D Slot 1: Value to be written in the codec register for a write operation
For a read operation, the DIN slot 1 is zero stuffed. Depending on the register to be read, the codec puts the
register contents on the slot 1 of DOUT in the same frame.
The following are examples of programming a TLV320AIC22 whose device address is set to 0 (AD0=AD1=0).
Example 1. Write Operation (R/W = 1):
Programming control register 15 of a device with address 0x00h with the data set to 0x23h results in the following
data being driven on the DIN pin for time slots 0 and 1:
Slot 0: 1 00 0000 1111 00000
Slot 1: 0010 0011 0000 0000
