The ISD5100 Series are controlled by loading commands to, or, reading 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.
Command Byte
Control of the ISD5100 Series are implemented through an 8-bit command byte, sent after the 7-bit
device address and the 1-bit Read/Write selection bit. The 8 bits are:
Function Bits
The command byte function bits are
detailed in the table to the right. C6, the
DAB
device is performing an analog or
digital function. The other bits are
decoded to produce the individual
commands.
combinations are currently used, and
are reserved for future use. Out of 16
possible codes, the ISD5100 Series
uses 7 for normal operation. The other
