These timing parameters are critical for proper control port operation.
The PCM3168A and PCM3168A-Q1 support an I2C-compatible serial bus and data transmission protocol for fast
mode configured as a slave device. This protocol is explained in the I2C specification, version 2.0.
The PCM3168A and PCM3168A-Q1 have a 7-bit slave address, as shown in Figure 51. The first five bits are the
most significant bits (MSB) of the slave address and are factory-preset to 10001. The next two bits of the
address byte are selectable bits that can be set by MS/ADR0/MD0 and MDO/ADR1/MD1. A maximum of four
PCM3168A and PCM3168A-Q1s can be connected on the same bus at any one time. Each PCM3168A and
PCM3168A-Q1 respond when it receives its own slave address.
