Voice Recording & Playback Device
Revision 1.0
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 types of data streams: Device status, Sili-
con ID, and user stored digital 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.
Figure 7 Data Out Timing
Current Device Status (CDS)
As described in the previous section, three different types of
data streams are shifted out on the DO pin as data is shifted
in on the DI pin. One of these streams is the current device
status. The CDS will be shifted out unless the previous com-
mand is SID command. Figure 8 shows the format of the
CDS bit stream. The first bit shifted out, D0, 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 ille-
gal address is sent to the device. The D3 bit is the Lbat flag.
This flag 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 cur-
rent or last active sector.
