Functional description
Refer to Figure 1 “Block diagram of SA58635”.
7.1 Device address
Following a START condition, the bus master must output the address of the slave it is
accessing.
The SA58635 responds to two slave addresses: 1100 000xb for standard accesses and
the General Call writes (0000 0000b) for software reset. The last bit of the address byte
defines the operation to be performed. When set to logic 1 a read is selected, while a
logic 0 selects a write operation.
When a reset of the I2C-bus needs to be performed by the master, the master will write to
the General Call address followed by a write of the reset command (0000 0110b). When a
General Call reset command is sent by the master, the SA58635 will respond with an
acknowledge and execute a reset to the digital logic. This will return the register set and
the volume controls to the Power-On Reset (POR) values.
7.2 Control register
Following the successful acknowledgement of the slave address, the bus master will send
a byte to the SA58635, which will be stored in the Control register.
The lowest 3 bits are used as a pointer to determine which register will be accessed
(D[2:0]). The remaining bits are not used and are ignored.
