PCM3060
SLAS533–MARCH 2007
The PCM3060 has 7 bits for its own slave address. The first six bits (MSBs) of the slave address are factory
preset to 10 0011. The next bit of the address byte is the device select bit, which can be user-defined by the
ADR pin (pin 27). Two PCM3060s at maximum can be connected on the same bus at one time. Each PCM3060
responds when it receives its own slave address.
A master device must control packet protocol, which consists of a start condition, slave address with read/write
bit, data if write or acknowledgement if read, and stop condition. The PCM3060 supports the slave receiver
function.
The PCM3060 supports the receiver function. A master can write to any PCM3060 registers using single or
multiple accesses. The master sends a PCM3060 slave address with a write bit, a register address, and the
data. If multiple access is required, the address is that of the starting register, followed by the data to be
transferred. When the data are received properly, the index register is incremented by 1 automatically. When the
index register reaches 4Ah, the next value is 40h. When undefined registers are accessed, the PCM3060 does
not send an acknowledgement.

is a diagram of the write operation. The register address and the write
data are 8-bit in MSB-first format.
