Revision B.4

7.5.2. Function Bits

The command byte function bits are

detailed in the table to the right. C6, the

DAB bit, determines whether the device is

performing an analog or digital function.

The other bits are decoded to produce the

individual commands. Note that not all

decode combinations are currently used;

they are reserved for future use. Out of 16

possible codes, the ISD5216 uses 7 for

normal operation. The other 9 are No Ops.

7.5.3. Register Bits

The register load may be used to modify

a command sequence (such as load an

address) or used with the null command

sequence to load a configuration or test

to the user. [The remaining three codes

are No Ops.]
