detailed description (continued)
control register address and data
When the I2C/SPI pin is tied to a logic low, the serial interface is selected for controlling the device. Control
information is sent and received in time slots 0 and 1. An active-high pulse on the FSYNC pin indicates the start
of a frame. The structure of time slots 0 and 1 is shown in Figures 5 and 6. Bit 15 (the MSB) is transmitted or
received first. Transmitted data is sent on the rising edge of BCLK and data being received is latched on the
falling edge of BCLK.
Time slot 0 indicates:
D If a read or write operation is occurring
D Which device is being accessed
D The register address within the device being accessed
AD0 (LSB) and AD1 (MSB) form the device address. Up to four TLV320AIC22 devices can be addressed, with
addresses ranging from 0 to 3. The five LSBs in time slot 0 are unused.

1 = Write, 0 = Read

Figure 5. Bit Assignment and Definition for Slot-0 Word
If bit 15 in slot 0 is a 1, a write operation has been requested by the DSP. The DSP drives data onto the DIN
pin in the next time slot (time slot 1) as follows:
D The 8 bits of data to be written into the register appear on the first 8 bits, with the MSB appearing first.
D The next 8 bits (8 LSBs) are unused.
If bit 15 in slot 0 is a 0 a read operation has been requested. The TLV320AIC22 compares the values of the
device address bits, bits 14 and 13 of time slot 0 (AD1 and AD0 bits) to the configuration of the AD1 and AD0
pins on the device to determine if it is the device being addressed. The device drives data on DOUT if it is the
addressed device, as follows:
D The 8 bits of data from the addressed register appear in the first 8 bits, with the MSB appearing first.
D The next 8 bits (8 LSBs) are unused.
Slot 1:
B15–B8
Control register data
B7–B0
Unused
