In the I
option is selected, the next two bytes are loaded into the selected register. The format of the data is
MSB first, the I
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:
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.

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.
