TFA9812
BTL stereo Class-D audio amplier with I2S input
9.3 I2C write cycle description
byte size is 8 bits. The I2C registers of the TFA9812 store two data bytes. Data is always
written in pairs of two bytes. Data transfer is always MSB rst.
The cycle format for writing to the TFA9812 using SDA is as follows:
1. The microcontroller asserts a start condition (S).
2. The microcontroller sends the device address (7 bits) of the TFA9812 followed by the
R/!W bit set to 0.
3. The TFA9812 asserts an acknowledge (A).
4. The microcontroller writes the 8-bit TFA9812 register address to which the rst data
byte will be written.
5. The TFA9812 asserts an acknowledge.
6. The microcontroller sends the rst byte. This is the most signicant byte of the
register.
7. The TFA9812 asserts an acknowledge.
8. The microcontroller sends the second byte.
9. The TFA9812 asserts an acknowledgement.
10. The microcontroller can either assert the stop condition (P) or continue with a further
pair of data bytes, repeating step 6. In the latter case the targeted register address will
have been auto-increased by the TFA9812.
9.4 I2C read cycle description
The byte size is 8 bits. The I2C registers of the TFA9812 store two data bytes. Data is
always read in pairs of two bytes. Data transfer is always MSB-rst.
The read cycle format for writing to the TFA9812 using SDA is as follows:
1. The microcontroller asserts a start condition (S).
2. The microcontroller sends the device address (7 bits) of the TFA9812 followed by the
R/!W bit set to 0.
3. The TFA9812 asserts an acknowledge (A).
4. The microcontroller writes the 8-bit TFA9812 register address from which the rst data
byte will be read.
5. The TFA9812 asserts an acknowledge.
6. The microcontroller asserts a repeated start (Sr).
7. The microcontroller resends the device address (7 bits) of the TFA9812 followed by
the R/!W bit set to 1.
8. The TFA9812 asserts an acknowledge.
