7.5. CONTROL REGISTERS
The ISD5216 is controlled by loading commands to, or reading commands from the internal command,
configuration and address registers. The Command byte sent is used to start and stop recording, write
or read digital data and perform other functions necessary for the operation of the device.
Control of the ISD5216 is implemented through an 8-bit command byte that is sent after the 7-bit
device address and the 1-bit Read/Write selection bit. The 8 bits are:
the DAB bit.
7.5.1. Command Byte
Global power up bit (PU)
DAB bit: determines whether device is performing an analog or digital function
3 function bits: these determine which function the device is to perform in conjunction with
3 register address bits: these determine if and when data is to be loaded to a register
