ISD5100 – SERIES

7.3.4. Data Bytes

In the I2C write mode, the device can accept data sent after the command byte. If a register load

option is selected, the next two bytes are loaded into the selected register. The format of the data is

MSB first, the I2C standard. Thus to load DATA<15:0> into the device, DATA<15:8> is sent first, the

byte is acknowledged, and DATA<7:0> is sent next. The address register consists of two bytes. The

format of the address is as follows:

ADDRESS<15:0> = PAGE_ADDRESS<10:0>, BLOCK_ADDRESS<4:0>

Note: if an analog function is selected, the block address bits must be set to 00000. Digital

Read and Write are block addressable.

When the device is polled with the Read Status command, it will return three bytes of data. The first

byte is the status byte, the next the upper address byte and the last the lower address byte. The status

register is one byte long and its bit function is:

STATUS<7:0> = EOM, OVF, READY, PD, PRB, DEVICE_ID<2:0>

Lower address byte will always return the block address bits as zero, either in digital or analog mode.

The functions of the bits are:

EOM

OVF

READY

PD

PRB

DEVICE_ID

BIT 7

BIT 6

BIT 5

BIT 4

BIT 3

BIT 0, 1, 2

Indicates whether an EOM interrupt has occurred.

Indicates whether an overflow interrupt has occurred.

Indicates the internal status of the device – if READY is LOW

no new commands should be sent to device, i.e. Not Ready.

Device is powered down if PD is HIGH.

Play/Record mode indicator. HIGH=Play/LOW=Record.

An internal device ID. ISD5116 = 001; ISD5108 = 010;

ISD5104 = 100 and ISD5102 = 101.

It is recommended that you read the status register after a Write or Record operation to ensure that

the device is ready to accept new commands. Depending upon the design and the number of pins

available on the controller, the polling overhead can be reduced. If INT and RAC are tied to the

microcontroller, it does not have to poll as frequently to determine the status of the ISD5100-SERIES.
