Receiving Device Information
The device communicates data to the user by
Shifting out data on the DO pin. The device will
shift out data according to the timing parameters
given in Figure 7.The device can shift out three
different
Current Device Status (CDS)
As described in the previous section, three
different types of data streams are shifted out on
the DO pin as
One of these steams is
status. The CDS will be shifted out unless the
previous command is SID command. Figure 8
shows the format of the CDS bit stream. The first
bit shifted out, DO, is the Overflow flag. The
Overflow flag is set to a binary 1 if an attempt was
made to record beyond the available memory. The
Overflow flag is set to a 0 if an overflow has not
occurred. This flag is cleared

after it has been read. The D1 bit is the End of
Data flag. The EOD flag is set when the device
stops playing, or fast forwarding as a result of an
EOD bit in memory. The EOD flag is cleared after it
has been read.The D2 bit is the Illegal Address flag.
The Illegal Address flag is set whenever an illegal
address is sent to the device. The D3 bit is the low
battery (Lbat) flag. Thisflag is set when the device
senses a supply voltage below specification. The
D4 bit is not used and should be ignored. The last
fifteen bits represent the address of the current or
last active sector.
types of data streams: Device status, Silicon ID and
user stored data.Device status and silicon ID are
described in the next two sections. Retrieval of user
data is described in the Reading Digital Data
section
