APR6016 Aplus Integrated circuits Inc., APR6016 Datasheet - Page 6

• Manufacturer Part Number: APR6016
• Description: Recording & Playback Voice Ic
• Manufacturer: Aplus Integrated circuits Inc.

The NOP command performs no operation in the
device.It is most often used when reading the
current Device status. For more information on
reading device Status see the Current Device
Status section.
THE SID operation instructs the device to return
the contents of its silicon ID register. For more
Information see the Reading the SlD section.
The SET_FWD command instructs the device to
fast forward from the beginning of the sector
specified in the OpCode parameter field.The
device will fast forward until either an EOD bit or
the end of the sector is reached. If no EOD bit or
forthcoming command has been received when
the end of the sector is reached,the device will
loop back to the beginning of the same sector and
begin the same process again. If an EOD bit is
found the device will stop and generate an
interrupt on the /INT pin. The output amplifiers are
muted during this operation.

The FWD command instructs the device to fast
forward from the start of the current sector to the
next EOD marker. If no EOD marker is found within
the current sector the device will increment to the
next sequential sector and continue looking. The
device will continue to fast forward in this manner
until either an EOD is reached, a new command is
sent, or the end of the memory array is reached.
When an EOD is reached the device will stop and
generate an interrupt on the /INT pin. The output
amplifiers are muted during this operation.
The PWRUP command causes the device to enter
power up mode and set the internal clock frequency
and EXTCLK divider ratio. To select an Internal
oscillator frequency set the [A1 – A0] bits according
to the following binary values:
