APPLICATION INFORMATION
I2C operation specific to the TPA0172 device
The TPA0172 operates using only a multiple byte transfer protocol as shown in Figures 29 and 31. The six
internal registers and the functionality of each can be found in Table 6. When writing to the device, all 6 bytes
corresponding to all six registers must be sent to the device in a single multiple byte transfer. During a read cycle,
the TPA0172 will send 6 bytes in a single transfer to the master device requesting the information.
