JAJSFI3A May 2018 – November 2018 TAS3251
PRODUCTION DATA.
A master can write to any TAS3251 device registers using single or multiple accesses. The master sends a TAS3251 device slave address with a write bit, a register address with auto-increment bit, and the data. If auto-increment is enabled, the address is that of the starting register, followed by the data to be transferred. When the data is received properly, the index register is incremented by 1 automatically. When the index register reaches 0x7F, the next value is 0x0. Table 19 shows the write operation.
