ZHCSIM2D June 2010 – August 2021 PCM9211
PRODUCTION DATA
A master can read the PCM9211 registers. The value of the register address is stored in an indirect index register in advance. The master sends the PCM9211 slave address with a read bit after storing the register address. The PCM9211 then transfers the data to which the index register points. Figure 7-32 shows the read operation.
