isd5216 Winbond Electronics Corp America, isd5216 Datasheet - Page 23

• Manufacturer Part Number: isd5216
• Description: 8 To 16 Minutes Voice Record/playback Device With Integrated Codec
• Manufacturer: Winbond Electronics Corp America

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.
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
register. Not all registers are accessible
to the user. [The remaining three codes
are No Ops.]
